No one likes talking to police, whether for DUI or questions in a criminals case of any kind. You have both rights and responsibilities, regardless of the crime being investigated. It's always useful to get an attorney on your side.
You May Not Need to Show ID
Many citizens are not aware that they aren't required by law to answer all an officer's questions, even if they were driving. If they aren't driving, they don't always have to show ID either. These rights were put into the U.S. Constitution and seconded by Supreme Court justices. You have a right not to testify or speak against yourself, and you may usually walk away if you aren't being detained or arrested.
Imagine a scene where cops think you have broken the law, but you are innocent. This is just one time where you should to get help from a good criminal defender. State and federal laws change on a regular basis, and differing laws apply jurisdictionally. This is particularly true since laws often change and court cases are decided often that make changes too.
Sometimes You Should Talk to Police
While there are times for silence in the face of legal action, remember the truth that most police just want to keep the peace and would rather not make arrests. You probably don't want to make cops feel like you're against them. This is another reason to get an attorney such as the expert lawyers at dui attorney eugene or on your defense team, especially for interrogation. Your lawyer can inform you regarding when you should volunteer information and when to shut your mouth.
Cops Can't Always Do Searches Legally
Unless police officers have probable cause that you you are a criminal, they can't search your home or vehicle without permission. However, if you begin to talk, leave evidence everywhere, or give your OK a search, any data collected could be used against you in court. It's probably smart to say no to searches verbally and let the courts and your defense attorney sort it out later.
