Occupiers banned from parks even when parks are open

Is it fascism yet?

It's bad enough for cities to close down public parks every night - a rule that was designed to be selectively enforced. But now they're singling out Occupy protesters by banning them from parks the rest of the time too.

In Portland, Maine, individual participants in Occupy Maine are now being banned from Lincoln Park even when the park is open - under threat of being charged with trespassing. The police-imposed bans are in force for up to a year.

I shouldn't even have to be saying this, but how can one be guilty of trespassing on public property - especially when the park is open? Did NKU take over the Portland Police when nobody was looking?
