Excellent example what a large crowd of people without weapons can do versus a group of goons with their helmets & shields that are literally protecting satanic communists and their satanic policies.

A constant rain of rocks can be thrown as each person from front to back recoils to yet throw another. As they move forward, those same rocks are on the ground where they can pick them back up and throw them again. A literal constant never-ending hail of rocks against those police goons.

Might be one strategy for European crowds showing up to protests. Every single person bring 2 rocks. If police want to throw out their flash bangers and tear gas, then here come the never-ending hail of rocks.
