what to do if you're arrested for participating in OWS.
Although there may not be any justification for an arrest and you don't like the way you are treated, you should always remain calm. Physically resisting arrest will be worse for you. You have the right to remain silent and you have the right to refuse consent for a search.
Most of the arrests for OWS are falling under disorderly conduct. It can be different for each state, but they are along those lines, impeding traffic, failure to disperse, creating annoyance, loitering, etc. It could result in a misdemeanor charge, jail time and a criminal record. Once out of jail, if you continue to OWS and another arrest happens, it could bring harsher penalties each time.
Understand your rights however. Here is a link that goes over your rights if you're stopped by police, including asking if you are free to leave and writing a complaint and contacting your local ACLU if you feel your rights are violated.
