The Occupy movement was not "peaceful". They squatted on public and private property for days and refused to leave. Eventually they had to be kicked out. Most people that were arrested were release and never charged unless they were caught vandalizing property or fought with the police.
These restore the fourth rallies look to me like real peaceful protests and not organized civil disruption like OWS so I doubt there will be mass arrests. So I say go and enjoy the day with like minded Americans.
How is the first part of that a distinction from peaceful protest? The "sit-in" is a pretty canonical form of nonviolent protest, made famous in the U.S. during the civil-rights era.
If your argument is that it was illegal, I can certainly believe that. But I'm having trouble determining how camping in a public square is a form of violent protest. That's the kind of argument the Turkish government is currently making.
