Why not just go through the protesters tazing every one of them, zip-tie them while they are face down. Then drag them off.
The Water cannon is a great option if it’s available
The fastest way to stop a riot is to isolate the leadership [cut off the head] and then go after the worst of the mob. Ist you get anyone with a bullhorn and throw them in the paddy wagon then you get the most enthustastic of the rioters cuff them and drag them away the rest are the sheep who are easily controlled. Cuff em and buss em was the word,From my experiance at the “Days of Rage” DC riots in the 70’s. I think we had some 7-8 thousand rioters rounded up at RFK stadium at one time. I ran out of wire ties.
