It's important to remember that the regime does not and will not have a superweapon it can use without severe consequences.
It's also important to remember that the agencies showing up to harm and intimidate vulnerable and disenfranchised populations are cowards and generally unintelligent.
Protests are good. It gives them something to get angry about. The angrier they get, the dumber they act. They want violence. They want retaliation. The longer they don't suffer casualties, the sooner they start making mistakes that cause them to weaken themselves.
Be an obstruction. Ruin their equipment. Broadcast their names and faces. Shame them.
If they resort to lethal force, it must not be responded to with violent resistance they expect. It must be unexpected resistance. It must make them question their actions. It must wake them up to the problem they have caused.
