Beyond the Badge: Exposing Flaws in Police Investigations

What does a thorough and unbiased police investigation look like?

David Drwencke explained that a proper investigation should gather all available evidence, follow every reasonable lead, and consider both incriminating and exculpatory facts. Police should interview all relevant witnesses, preserve video or physical evidence, and avoid jumping to conclusions. He emphasized that investigations must remain objective, not focused solely on building a case against a single suspect.

What are the most common flaws in police investigations?

According to Drwencke, the most frequent flaw is confirmation bias—when investigators develop blinders and focus only on evidence that supports their initial theory. This often results in ignoring contradictory evidence, overlooking alternative suspects, or failing to fully test the accuracy of victim or witness statements.

How do defense attorneys identify flaws in police work?

Drwencke noted that criminal defense attorneys analyze discovery materials, including police reports, body cam footage, surveillance video, and witness interviews, to identify inconsistencies. Red flags include missing reports, uncollected evidence, or testimony that doesn’t align with the physical or video evidence. These weaknesses can become central to the defense strategy at trial.

What role do body cameras and surveillance play in today’s investigations?

Drwencke emphasized that body-worn cameras, pod cameras, license plate readers, and even residential Ring doorbells have become crucial tools in testing the credibility of police testimony. Video evidence often provides objective proof that can confirm or contradict an officer’s account, making it one of the most valuable resources for defense attorneys.

What happens when video evidence is missing or not preserved?

Missing or destroyed video can significantly impact a case. Drwencke explained that when key footage is lost, defense attorneys can argue that the investigation was incomplete or negligent, raising doubt in the minds of jurors. Sometimes, the absence of video evidence itself becomes a powerful argument for reasonable doubt.

Do juries automatically trust police testimony?

Historically, juries placed significant trust in police testimony. However, Drwencke observed that in recent years, jurors have become more skeptical due to high-profile cases of police misconduct. While some still defer to law enforcement, more jurors today are willing to question whether officers conducted thorough and fair investigations.

Can you share examples of cases where investigative flaws made a difference?

Yes. Drwencke recounted a sexual assault case where investigators failed to verify key facts that could have disproved the allegation. The oversight created reasonable doubt and significantly helped the defense. In another case, body cam footage contradicted officer testimony in a gun possession charge, ultimately undermining the prosecution’s credibility and leading to a favorable outcome for the defendant.

Why is it important for defense attorneys to challenge investigative shortcuts?

Drwencke stressed that unchecked investigative shortcuts can lead to wrongful convictions. Defense attorneys must expose these flaws to ensure fairness and to hold the prosecution accountable. By pointing out what police failed to do, defense attorneys create reasonable doubt and protect constitutional rights.

What final advice did David Drwencke share about flawed investigations?

Drwencke concluded that defense attorneys should never assume that a police investigation is complete or unbiased. By scrutinizing every step of the process and highlighting gaps or biases, attorneys can reveal the truth, protect their clients, and maintain integrity within the justice system.
