It may not be a crime, but if you are a runaway or out of the control of your parents, then the police can generally haul you back home. In some states (and AZ may be one of them) the police cannot forcibly return a 17-year-old home.

Additionally, even if they will not return YOU, the people that are aiding you in being out of your parent's control could be charged with crimes relating to custodial interference or contributing to your delinquency. In short, you may get your friends arrested.

Have you thought to ask the local police what they would do?
