Did they fire those guns? Assualt anyone? Burn down a building or two? Turn over any vehicles? Any act of violence at all? Peaceful protests are legal. So is owning a gun. Your argument is completely incorrect in comparison of the two groups in question.
I am comparing protests to protests, it is sad the looters and rioters took advantage of the situation.
But the police used tear gas and rubber bullets against the protestors who were peacefully standing around while they ignored the looters and people causing damage.
Thank you for admitting that peaceful protests are legal.
So why did the police attack peaceful protestors or yank 2 students out of a car and taser them and break the windows?
