"Earlier today, sporadic clashes happened when groups of plainclothes men attacked forming gathering of young Iranians."

Your own people are going to have to deal with this. You need to form triplets of
people with the discipline to observe these attacks without interfering. Follow the group
of thugs, and pick off "tail end charlie". In these groups there is always some stupid
ba$tard that misses the signal to move on and gets himself seperated. It will be the most
heartwrenching thing to endure seeing someone beaten, stabbed, and maybe slain.
But, disciplined action will reduce casualties in the long run.

RE #21

Yes, some basic guerilla tactics are in order. In addition to your tactic, they should create many small groups of at most a few dozen, and move into an unguarded place and do a quick protest to draw attention of vigilantes and escape into alleys before thugs get to them, only to regoup again in another unguarded place and protest again. This would make vigilantes really disoriented.

Follow the group of thugs, and pick off "tail end charlie".

Another good tactic is the "running ambush": Have a small group do a protest and wait for thugs. When thugs appear, run into nearby alley and have thugs chase you. Thugs soon discover they have just run into an ambush as the rest of your group either surround them, or toss Molotov cocktails at them from windows and rooftops
