Your link isn't working for some reason.

Keep in mind that it's common for governments and other political organizations to insert agitators for the purposes of attempting to discredit or change the message of a protest. Happens very frequently.

Also there is a large contingent of people that just like rioting. IE: "Now could be your only chance to torch a police car"
