How Criminal Defense Challenges Prosecution Evidence

 There are many strategies for defending against criminal charges, and one common approach is to challenge the evidence the prosecution presents against you. This is no simple task, especially because the prosecutor will be working to present persuasive evidence to obtain a conviction whenever possible.


At the Law Office of Richard F. Matthews, Jr., we understand the steps in challenging evidence and the importance of examining this possibility in every criminal matter we handle. Contact our Alabama criminal defense lawyer today to discuss your arrest and/or charges.


The Importance of Challenging a Prosecutor's Evidence Against You

When faced with criminal charges, the prosecution must prove your guilt beyond a reasonable doubt to convict you of a crime. They do so by presenting evidence of your guilt to the court. By successfully challenging their evidence, you can weaken their case significantly and cast doubt in the minds of the judge or jury. If there is reasonable doubt in their minds, you should not be convicted.


Experienced Alabama criminal defense attorney Matt Matthews can identify weaknesses in the prosecutor's evidence and strategize the best defense for your case.


Challenging Forensic Evidence


Chain of Custody

One common strategy for challenging forensic evidence is questioning the chain of custody. This involves examining the documented trail of where the evidence has been since its collection. Any gaps or inconsistencies in the chain of custody can raise doubts about the integrity of the evidence and its admissibility in court.


Mishandling Evidence in Forensic Labs

Forensic evidence is often key in criminal cases, but it is not infallible. Errors or misconduct in forensic labs can compromise the validity of the evidence. By challenging the handling and analysis of forensic evidence, your attorney can cast doubt on its reliability and credibility.


Challenging Witness Testimony

Depositions

Depositions are pre-trial testimonies given under oath outside of court. By conducting depositions of witnesses, your attorney can uncover discrepancies or inconsistencies in their statements. Challenging witness testimony through depositions can weaken the prosecution's case and bolster your defense.


Cross-Examinations

During trial, cross-examining witnesses allows your attorney to challenge their credibility and poke holes in their testimony. Skilled cross-examinations can expose biases, motivations, or inaccuracies in witness statements, undermining the prosecution's case against you.


Getting Illegally Obtained Evidence Suppressed

Sometimes, evidence against you is obtained illegally, such as through an unlawful search or seizure or following an illegal traffic stop or arrest. If your defense lawyer identifies constitutional violations of your rights, it may be possible for them to have that evidence suppressed by the criminal judge. Suppressing illegally obtained evidence requires technical legal arguments and motions, but if successful, it can significantly weaken the prosecution's case and increase your chances of a favorable outcome.
