Not all Antifa and affinity groups are “limp-wristed fairies”. Some are tough Marxist/psychopathic street fighters. They are the most dangerous and if they attack, they must be taken down in the first for seconds before their reinforcements come to their aid.
Since you can’t legally defend yourself with weapons in DC (only communists, BLMers and psychopaths are allowed to use weapons), our people need to know how to do a take-down by using the football technique of “Hi/Low” hits (below the knees and at the waist level - Got a scar from being hit by a bunch of ahole touch-football players in college - I went to the hospital but so did others I helped to reeducate on the rules of the game).
Also, shining LEGAL lights in their faces helps to stun/stop their forward motion. Also spraying shaving cream under pressure should stop a bunch of them (and make them smell a lot better in the deal).
Leg sweeps. Saw the Mother of All Leg Sweeps used against an Antifa rioter in Seattle or Portland. Sent the commie flying into the street/sidewalk on the side of his head. he did not get up.
Water - spraying a legal bottle of water in their faces esp. on a cold January day would be a major contribution to improving their personal hygiene. Deer Park as a one-liter bottle with a spray mechanism on top. Otherwise, hit the bastards in the face, top of the head, balls, kneecaps and ankles with it, esp. if it partially frozen.
The old Ankle Kick or Step On. This technique was advocated by the police for women to use against an advancing attacker or one who already had grabbed her from behind or the front (step back on the ankle if the attacker comes from behind; kick or stomp on directly if coming from the front. Then kick them in the nuts just for good measure).
Don’t forget the hand to the throat if you are in serious trouble. Open hand, hand chop or closed fist can save your life but should only be used as a last alternative life-protecting move).
Fingers in the eyes is also a winner.
Just a few tips I learned from the police, in wrestling, some street attacks, and as Alan Rickman said in “Die Hard”, “I read it in Newsweek”.
You forgot sharp stroke upward heel of hand to nose. Lethal when done properly.
I'm going to do a three stooges deep dive to prepare. :-)
