Chalk "Black Lives Matter" on the sidewalk, go to jail for a year

Hold on… people wrote messages on their own bodies, and some City dude came along and hosed them down to remove those messages?

Isn’t that assault and suppression of free speech?

Hell, if those people wrote ‘I heart KKK’ on their bodies and the City hosed them down then folks should still be outraged.

Sigh. Where is the Federal Government on this? FBI?
