Self-Incrimination Protections

A person’s Fifth Amendment rights protect him/her from self-incrimination. This includes turning over protected passwords on cell phones, laptops, and other electronic devices to police officers looking for evidence. If arrested for a crime, a person may not be forced by law enforcement to unlock electronic devices with personal passwords or biometric passwords that divulge personal information.

With advancements in technology, cell phone, tablet, and computer users are given heightened security for their devices. To prevent security breaches and hackers, the latest electronic devices permit users to lock and unlock devices and protect their passwords in numerous ways.

Personal Passwords

When obtaining evidence in a crime, the court can require alleged suspects to turn over physical evidence to law enforcement. However, if the evidence is held mentally, rather than physically, it does not have to be turned over. Under Fifth Amendment rights against self-incrimination, electronic devices unlocked with personal passwords known only to the user do not have to be shared in court.

Biometric Passwords

Biometric passwords rely on a person’s physical features such as fingerprints, facial features, and retinal images to unlock an electronic device. Until recently, the court made a distinction between personal passwords committed to memory and biometric passwords that use physical features. Since fingerprints and facial recognition images are something a person has, rather than something a person knows, police officers have previously been permitted to unlock electronic devices with biometric passwords to obtain evidence.

The rights of an individual under the Fourth and Fifth Amendments are protected in criminal cases. Recent rulings argue that personal passwords and biometric passwords should be given the same protection under the law. If these types of passwords are turned over to obtain evidence in a criminal case, a defendant’s Fourth Amendment rights against illegal searches and seizures, as well as Fifth Amendment rights against self-incrimination would be violated.

Depending on the district, court rulings vary on unlocking electronic devices with biometric passwords. Until the U.S. Supreme Court issues a clear ruling on this issue, electronic devices with biometric passwords may not be protected under Fifth Amendment rights. If arrested for a crime, a criminal defense lawyer can explain a defendant’s legal rights concerning personal passwords and biometric passwords in obtaining evidence.

What to Do If You Have Been Charged with a Criminal Offense

You may need to hire a criminal defense lawyer even if you have not been charged. A criminal defense lawyer protects your rights when law enforcement officers are investigating you for a crime. Without a lawyer, you might say something that could be incriminating or misconstrued. Your lawyer can engage with the police or the prosecutors and provide evidence that prevents them from filing formal charges. Your lawyer can also go through your case and prepare a defense strategy if there is a possibility of you getting charged.
People arrested or charged with a crime may wonder, “How long do I have to get a criminal lawyer?” There is no strict deadline to hire a criminal lawyer in Minnesota. However, it’s advisable to hire one immediately if you get arrested, charged, or are under investigation for a crime. Getting legal representation on time protects you from making mistakes that can compromise your case. It also allows your lawyer to build a solid defense strategy that can increase your likelihood of getting a positive outcome from your case.
Continuance is what a court grants to delay proceedings. The parties in a criminal case (the prosecution and defense teams) may agree to a continuance to get more time to prepare for the proceedings. There are many reasons that push your defense lawyer in Minnesota to seek a continuance. A good example is when the other party presents surprise witnesses or evidence, requiring more time to work on a new defense. You can also request a continuance if you want to replace your lawyer, especially if you feel you are not getting sufficient representation.
