The revolution certainly isn't going to be pain free. I imagine even that quite a few people will die in the process. But freedom was never guaranteed to be free. Even Thomas Jefferson felt that revolution was good for this country every generation and we're running a little late on that.
As long as we still adhere to the original constitution and bill of rights we will be fine. All thats really needed is that our elected leaders start taking responsibility for what they have done to this country. And it crosses political lines. The OWS movement has been very disappointed in Obama's presidency and rightfully so.
I think all of us wish for the transition to be as peaceful as possible but thats just not very realistic. All we have to do is look at our own history to see that nothing meaningful has been accomplished with purely peaceful protests.
