Well it really depends...
Are they just arresting campers with tents, or are they arresting protesters who aren't doing anything? If the latter, then I would let them arrest me, and make a court challenge.
Back in the 60's and 70's, civil disobedience and peaceful protest lead to a lot of people being arrested, but those people would be released almost immediately after. Then they would just go right back to the protest site and sit back down again.
The people who are attacking police and being rude need to learn a thing or two from their precedessors.
The other thing people have to realize is, the civil disobedience of the 60's and 70's was highly effective. It's why most major cities in North America now have designated protest zones. You can't exercise your First Amendment rights without getting a permit, and to get a permit you need to locate your protest in a designated zone. Those zones tend to be out of the way where they won't have any impact or visibility.
At some point Americans are going to have to just say no to disbandment, and keep protesting. Permits for peaceful gatherings are unconstitutional and need to be challenged. I accept if the city is removing campers; but if they are removing peaceful protesters who only have their person there, then it's unjustified.
IMO modern Americans have lost the ability to effectively protest. That includes the Tea Party, the Occupy movement, etc. Americans have been neutered of activist power.
