No one likes dealing with the cops, whether for DUI or questions in a criminals case of any kind. You have both rights and responsibilities, in any situation. It's almost always valuable to get an attorney on your side.
You May Not Need to Show ID
Many citizens are unaware that they don't have to answer all police questions, even if they have been pulled over. If they aren't driving, they may not have to show identification. 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 can almost always just leave if you aren't under arrest.
Even law-abiding people need criminal defense lawyers. Whether or not you've done anything wrong such as driving while drunk or speeding, you should take advantage of the protections available to you. State and federal laws change regularly, and disparate laws apply based on jurisdiction and other factors. It's also true that laws occasionally get changed during legislative sessions, and courts are constantly making further changes.
There are Times to Talk
While there are instances when you should be quiet in the legal matters, remember the truth that most officers just want to keep the peace and would rather not take you out. Refusing to talk could cause trouble and endanger the neighborhood. This is another instance when you should hire the best criminal defense attorney, such as criminal defense lawyer Portland OR is wise. Your lawyer can inform you regarding when you should give information and when staying quiet is a better idea.
Question Permission to Search
You don't have to give permission to search your house or car. However, if you start to blab, leave evidence lying around, or grant permission for a search, any data gathered could be used against you in future criminal defense proceedings. It's probably good to deny permission for searches verbally and let the courts and your attorney sort it out later.
