It's wise to believe that cops want what's best for everyone, but it's a good idea to be aware of your rights. Police have access to so much power - to take away our liberty and, occasionally, even our lives. If you are involved in a a criminal defense case or investigated for drunken driving, make sure you are protected by a good lawyer.
Police Can't Always Require ID
Many citizens don't know that they don't have to answer all an officer's questions, even if they have been pulled over. Even if you do have to prove who you are, you generally don't have to answer other questions officers might have about anything such as your recent whereabouts and activities or what you've been drinking, in the case of a drunken driving stop. These rights were put into the U.S. Constitution and affirmed by the courts. You have a right not to incriminate yourself, and you can almost always just leave if you aren't being detained or arrested.
Imagine a scenario where officers believe you have broken the law, but you aren't guilty. This is just one time where it's in your best interest to get help from a top-tier lawyer. Knowing all the laws and being familiar with the various situations in which they apply should be left up to qualified attorneys. It's also true that laws occasionally get changed during deliberative sessions, and courts of law are constantly making new rulings.
Usually, Talking is OK
While there are times for silence in the legal matters, remember how most police really want peace and justice and would rather not take you in. You don't want to make the police feel like you hate them.

Cops Can't Always Do Searches Legally
You don't have to give permission to search through your home or vehicle. However, if you start talking, leave evidence of criminal activity in plain sight, or grant permission for a search, any data collected could be used against you in future criminal defense proceedings. It's usually good to deny permission.
