I agree with you. Outside of sarcasm, I’m tempted to apply this version of the word:
“We’ll give you a fair trial, followed by a first-class hanging.” –Sheriff Cobb in Silverado
I don’t think violence is really the right answer to this mess, but I have to keep telling myself that. The hardest thing about facing down awful and destructive people isn’t winning, it’s not becoming them in the process.
As a practical matter, most or all of these people are wearing body armor. It isn’t full coverage, but it would make shooting them effectively a great deal more difficult. They also operate in large groups, which makes attacking any one of them a lot more dangerous.
The first civilian to shoot at them will almost certainly be killed within seconds. Anyone nearby is also likely to be hit, either accidentally or intentionally. Uninvolved civilians anywhere nearby are also likely to be hit. The agents are unlikely to care about their backstops or about collateral damage.
Any attack on possible government agents that is not part of a well-planned group response, using appropriate weapons, is going to result in civilian casualties and is unlikely to have any effect on the agents. That is not to say it couldn’t be done, but a few people responding with concealed carry weapons are not likely to succeed.
