there needs to be at least 10 of us with knives and aluminum bats hitting right back.

No, because that will make them open fire...

What will work is protesters in plated vests with rifles.

Every state is different. For Minnesota it's illegal to open carry a rifle, and there's no permit to open carry a rifle. But if you get a permit to carry a handgun, you're now allowed to carry a rifle.

The threat of effective violence is more effective than the actual act of ineffective violence, even when the threat is just passively implied by the presence of rifles and plates.

It costs less than a grand to get kitted out just like an ICE agent, hell, most of them don't even seem to carry rifles, but all the more reason for protesters.
