I used to work security for racing events. Ive had to detain more than more fair share of assholes. I am not a good fighter, but I can pretty much anyone on the ground and restrained ready for pick up by the cops. What we saw here in this video, was a joke. That wasnt any kind of trained person looking to detain someone. That was as amateur as it gets. That was like a comedy skit of how undertrained these supposed ICE agents are.
If you see someone trying to restrain someone, and it looks like this. They are not professional people. They are more than likely MAGA ICE fanboys kidnapping someone. Defence of self and/or others applies. If you dont want to do that, call the cops. Report a kidnapping in progress. Lie if you want, and claim its a child abduction. They will come running then.
