Can Protests cause riots

[Zinal]

Like, I had a protest in school about Immigration. The protest went fine until some people were running down halls and getting out of class and one person stab someone during the protest. I thinking about how protests are to be done peaceful. I would like to hear your opinions about it.

I'm reminded of something an American quack said once. I believe the chap's name was Jack Handey, yes.

"I can picture in my mind a world without war, a world without hate. And I can picture us attacking that world, because they'd never expect it."
