I feel like we need to have some sort of refresher course on protests because I saw someone say the same thing when some protestors were arrested for staging a "die in" (?) in the middle of the street in Washington DC, preventing thousands of people (99% of whom didn't work for the DoD and most of whom were AFSCME union members) from getting to work.  These are ten words everyone needs to remember when they're planning their next protest:

If you break the law, you will go to jail.

It's also ten syllables long, so please feel free to write it into a sonnet if that will help you remember it.

If the likely consequence is acceptable to you, feel free to break the law.  If it's not, then don't do it.  Either way, don't be surprised that this is a possible consequence; the relationship of cause::effect does not get suspended just because you happen to care about something.  Just like the laws of gravity, Coulomb's law and the laws of thermodynamics, laws against disorderly conduct are still in effect during a protest.

"We didn't mean to cause any harm to the city," said Marley Green, a 22-year-old college student from Harrisonburg, in statement released by the group. "We felt the action was a necessary step that had to take place."

Green was the most visible player in the protest, which began by surprise Monday at 7 a.m. He dangled in a climber's harness from the pedestrian footbridge to Belle Isle for more than two hours, while four other protesters blocked the street with their hands locked into containers of hardened cement.

"We felt the action was a necessary step..."

Then he of course realizes what may result as an outcome.  I agree, there's nothing crazy here.
