When you are arrested, the officer will be required to read your rights to you. This includes your right to remain silent. While officers are likely going to try to get you to say something that may later be used against you, it is often a good rule to wait to speak to them until you have legal representation present there to protect you. Officers will often try to get to you before your attorney is with you and they may pressure you in a number of ways. Don't play into this and wait until your attorney tells you to speak with them.
