Yes, and a few days ago some "peacekeepers" in UT tried to shoot someone whom they perceived to be a threat, and ended up shooting and killing a bystander nearby. Situations are complicated, and assuming you know what's going on, and that you can help, is presumptuous.

That argument works better against the position: things which create confusion increase the odds of serious problems. Reducing uncertainty by having clear rules makes it safer for everyone: that “good guy with a gun” is far more likely to be involved in a tragic mistake not because they have any desire to be but because it’s a snap judgement with limited information and bystanders. Armed paramilitaries abducting people in a manner indistinguishable from a cartel kidnapping or police impersonation is dramatically increasing the risk to those officers snd everyone nearby for the same reason, and they’re not doing anything they couldn’t do without following the law with identification, serving legal warrants, etc.
