Before you’re named as a suspect, the police will likely begin to question you. You have the right to remain silent and hire an attorney, even if you are not being charged with a crime. This can help protect you from being coerced into a confession for a crime for which you did not commit, and can also help protect your rights in the event that you are named a suspect later on down the line.
When you’ve been arrested and/or charged with a crime, you should contact an attorney immediately. If there is a warrant out for your arrest, you should obtain counsel as well. Your attorney will help you understand the case completely and will discuss the defenses available to your situation. Further, your attorney will help you understand if reducing or changing charges is an option, as well as negotiating a plea bargain for a reduced sentence if you wish to do so.
