Am I entitled to legal counsel?

The U.S. and Illinois Constitutions guarantee your right to legal counsel before you speak to anybody, including police, but you can waive that right by agreeing to talk to police or even your friends and family. Therefore, do not speak to anybody about your matter in any way, unless you are willing to pay the consequences of waiving your rights.

If I do not believe I did anything wrong, can I resist an arrest?

Do not resist arrest in any physical manner, as that is illegal and can result in another charge against you of resisting arrest. You can refuse to speak to officers, but do so politely and otherwise cooperate physically even if you believe the arrest is invalid or unlawful.
