I was just reading this story in LBN:
http://www.democraticunderground.com/discuss/duboard.php?az=show_mesg&forum=102&topic_id=1212368&mesg_id=1212368A peaceful student sit-in turned unruly at Manual High School, and school police used a chemical spray to disperse the crowd Thursday afternoon.
Duncan Pat Pritchett, the Indianapolis Public Schools superintendent, said it appeared officers overreacted by using the spray.
"Students do have First Amendment rights," he said.
About 100 students were in a hallway when police sprayed several bursts of the chemical in the air to disperse the crowd. No injuries were reported.

So, we have pepper spray cannons used on protesters at the coronation. We have chemical spray used on protesting high school students in their own school. It's safe to say that things have gone too far; I know protesters sometimes do get out of hand--throwing rocks at the presidential motorcade is not a very intelligent idea. However, police reaction to these individual acts has become far too strong, and has caused unnecessary harm to completely innocent people.
How are we going to protest at all if we always have to worry that police are going to use one person's bad judgement as an excuse to attack us all? We have to do something to protect ourselves without breaking the law. I think we should start wearing swimming goggles, to protect our eyes, and surgical masks, to protect our nose, mouth, and upper respiratory tract, whenever we "peacefully assemble to petition the government for a redress of grievances." The use of these items may not prevent all the damaging effects of pepper spray, etc., but I think they would certainly downgrade their severity, even if they make us look a little silly.
