At its very core, criminal defense is about protecting the rights of the accused, ensuring a fair trial, and holding the prosecution to its burden of proof. When you are charged with a crime, it does not automatically mean you are guilty or that you will be convicted. The US legal system operates on the principle that individuals are presumed innocent until proven guilty beyond a reasonable doubt.
At The Valley Law Group, we believe that no one should face criminal charges alone; in the US, you have the right to an effective legal defense. This is especially important as the potential consequences of a criminal charge are serious, including potential incarceration, hefty fines, and a long-lasting criminal record.
To secure your best chance at a positive outcome in your case, your defense attorney will build a custom-tailored defense, but even the most personalized defense strategy often hinges upon one of several common arguments. Understanding which of these legal strategies may be used to fight your criminal charges, we recommend that you consult with a qualified criminal defense attorney. They can evaluate your situation, explain your rights, and develop a personalized defense strategy to protect your future.
Top Legal Defenses in Arizona Criminal Cases
While every case is unique and any defense utilized will depend upon the facts surrounding the incident in question, there are several common defenses that can be employed. These strategies are meant to challenge allegations, mitigate penalties, or even lead to a dismissal of charges.
Innocence
The innocence defense is a common strategy where your legal team argues that you did not commit the crime. The defense typically aims to demonstrate that the defendant was not present at the crime scene when the crime occurred or did not partake in the crime. Alternatively, an innocence defense could also argue that the prosecution lacks sufficient evidence to support its claim that you were involved.
False Confessions
Law enforcement officers are sometimes known to utilize coercive tactics, including threats, sleep deprivation, or starvation, to elicit confessions. These methods can lead to false confessions, which are a severe form of police misconduct.
A widely known case in which a false confession was obtained was with the Central Park Five in 1989. Five teenagers were convicted of raping a jogger in Central Park after confessing with inconsistent statements and no physical evidence. Their confessions came after hours of aggressive, unrecorded interrogations. They were later exonerated and received a settlement from New York City.
Alibi
An alibi defense argues that you could not have committed the crime because you were in a different location at the time the crime occurred. While it is similar to the general innocence defense, an alibi specifically presents evidence that establishes you were elsewhere. Evidence could come in the form of witness testimony, video footage, shopping receipts, work timesheets, and more.
Self-Defense / Defense of Others
The self-defense or in defense of others argument asserts that you used force to protect yourself or others from imminent harm. As such, while you may have committed an act, you only did so to defend yourself against a threat.
The key is to prove that the force used was proportionate to the threat faced, as well as to prove that:
- The harm was an immediate threat. You can’t claim self-defense or defense of others for a threat that happened in the past or could happen in the future.
- You genuinely believed that the force was necessary to prevent harm to yourself or to another person.
A well-known self-defense case is the 2012 Florida v. George Zimmerman case. Zimmerman fatally shot Trayvon Martin during a confrontation after claiming Martin was on top of him, attacking him. The jury accepted his self-defense claim, and he was acquitted.
Lack of Intent
To successfully convict an individual of many criminal charges, the prosecution must prove that they intended to commit a crime. For these cases, a lack of intent can be a powerful defense. For example, if someone is accused of arson but the fire was accidental, the defense may argue that there was no intent to break the law. The lack of intent defense is especially popular in cases involving negligence or vehicle accidents.
Entrapment
Entrapment occurs when a law enforcement officer persuades someone to participate in a crime they would not have otherwise committed. An entrapment defense asserts that you were not going to commit the crime, but did so because of the officer’s actions.
The entrapment defense successfully worked in Sherman v. United States, a 1958 case where a man in addiction recovery was repeatedly asked by a government informant posing as a fellow addict to help obtain drugs. Sherman eventually relented to the pressure and was arrested. The Supreme Court reversed his conviction after ruling that the government had implanted a criminal idea in his mind, which led him to act.
Violation of Constitutional Rights
Your legal team could use a constitutional rights defense when your constitutional rights were violated during the investigation or prosecution of your case.
For example, this defense can be raised if there were violations involving:
- Your right to an attorney
- Your right to a fair trial
- Your right against self-incrimination
- Your Fourth, Fifth, Sixth, Eighth, or Fourteenth Amendment rights
If any evidence was obtained during these violations, your attorney could argue to have it excluded from your trial. If it represented pivotal evidence, it could mean the dismissal of your case.
Insanity
Your attorney may choose an insanity defense if your mental illness or defect at the time of the crime prevented you from understanding the nature of your actions. This defense requires a high burden of proof, typically based on testimony from a psychiatrist or psychologist.
A notable example of a case where an insanity defense played a central role is that of John Hinckley Jr., who attempted to assassinate President Ronald Reagan in 1981. He was found not guilty by reason of insanity after it was determined he suffered from severe mental illness. He was committed to a psychiatric hospital and conditionally released in 2016.
Mistake of Fact
A mistake of fact defense argues that you should not be held responsible for a crime because you genuinely believed a fact, even though it was incorrect. Essentially, an attorney will explain that your actions stemmed from an honest misunderstanding and not criminal intent.
For instance, if someone is accused of theft but honestly thought the item they took belonged to them, they could use this as a defense. This is not universally applicable, but it can be effective in cases where the prosecution must prove that you acted with specific intent or knowledge.
Mistaken Identity
A mistaken identity defense argues that you were not the individual who committed the crime. This can be supported by alibi evidence, witness testimony, or forensic evidence.
A case of mistaken identity was central to the case of Keyherra Green, who was arrested for murder. Her name and appearance were similar to the actual suspect, whose name was Keara Green. Keyherra was booked on murder charges until her attorney was able to prove she was not Keara Green.
Statute of Limitations
A statute of limitations defense is used when the prosecution takes too long to file charges against you. The specific time limit for bringing charges will depend on the crime and jurisdiction. Many Class 2-6 felonies have a 7-year statute of limitations, misdemeanors usually have a year, but more serious charges have no statute of limitations, including homicide and violent sexual assault.
Consent
The consent defense argues that the alleged victim willingly agreed to the actions that are now considered a crime. This defense is often used for sexual assault cases, where a defendant might claim the encounter was consensual.
In 1997, the defense team, arguing People v. Jovanovic utilized the consent defense. Oliver Jovanovic was convicted of kidnapping and sexual assault, but his legal team argued that the alleged victim had consented to the acts. His conviction was overturned on appeal because digital communication established consent.
Inaccurate Lab Results
If you are facing charges related to drugs or alcohol, such as driving under the influence (DUI), your legal team might be able to challenge the prosecution’s case by arguing that the lab tests were inaccurate. For drug cases, the defense could argue that the substance found was not a controlled substance. For DUI cases, an attorney could claim that the breathalyzer device was faulty or malfunctioned, or that the lab drug test was falsified.
An example is a case involving Annie Dookhan, a forensic chemist in Boston who was caught falsifying drug test results, tampering with evidence, and fabricating reports to appear more productive at work. Her misconduct affected over 20,000 criminal cases, which led to mass dismissals of convictions.
Duress Defense
When someone is forced to commit a crime because they or someone else has been threatened with harm or death, the duress defense could be used. In such cases, the defense team may argue that you had no alternative but to commit the crime to ensure you or others remain safe.
A notable example of the successful use of the duress defense is in the 2021 case United States v. Marjory Dingwall. Dingwall was charged with multiple counts of robbery and brandishing a firearm. She admitted to committing the crimes but claimed that she did so while under duress. She feared brutal violence from her abusive boyfriend, Aaron Stanley.
Dingwall and her defense team used professional testimony on the psychological effects of abuse to support her claim. The abuse she experienced was a mitigating factor, and she was sentenced to thirty months and one day in prison and three years of supervised release.
Providing Reasonable Doubt
In a criminal prosecution, the burden is on the prosecution to prove the defendant’s guilt beyond a reasonable doubt. This is a demanding legal standard that requires the evidence to be so convincing that there is no other logical explanation for what happened. If your defense attorney can demonstrate that the prosecution has failed to meet the “beyond a reasonable doubt” standard, you may be acquitted.
Choosing the Right Defense Strategy
The right defense strategy, when facing criminal charges, is one of the most critical decisions you and your legal team can make. Every case is unique, shaped by the facts, the evidence, the individuals involved, and the applicable laws. That is why it is essential to work with an experienced attorney who can assess the ins and outs of your situation and determine an effective path forward.
In many situations, a combination of defenses may be necessary. For example, a case might involve both an alibi and a challenge to the credibility of a key witness. Alternatively, it may require asserting that your constitutional rights were violated while also presenting mitigating circumstances. A layered defense can create reasonable doubt from multiple angles, thereby increasing the chances of a favorable outcome.
Timing is just as important. The earlier you begin working on your defense, the more options you may have. In some situations, it is possible to intervene before charges are even filed, which could help you avoid prosecution entirely. Early action allows your attorney to gather evidence, interview witnesses, and negotiate with prosecutors from a position of strength.
If you suspect you are under investigation, don’t wait; consult with a defense attorney as soon as possible. This could make a significant difference in the trajectory of your case.
Why Top Legal Counsel Is Essential
Navigating the criminal justice system without legal representation is a high-stakes gamble with your future. The law is complex, and even a seemingly minor misstep can have detrimental consequences. Without an attorney, you may not fully understand your rights, the charges against you, or the most effective way to respond.
Prosecutors thrive on aggressively pursuing any angle they can find to demonstrate your guilt. Their job is to secure convictions, and they know how to use the system to their advantage. This is why you need a legal team in your corner who understands how the system works as well, and someone who can anticipate the prosecution’s moves and counter them.
