Direct action, propaganda of the deed is ongoing here in my hometown. The state is having a recordbreaking wildfire season and the surrounding states are also feeling the effects. Utah and Texas are struggling to contain it. The explosion of graffiti is also obvious.
But fire comes with negative externalities. People, including yourself can get hurt. It also ensures an insurance payout that you have no desire to see come into the hands of people you might not like. It also exhausts a supply of labor that is financially inexhaustible. It also creates negative attention that you do not need.
The next evolution of protest should be low-risk and high reward like fire, but mitigates some of the negative attention. If the people know how to operate heavy machines in the day, they can operate those same machines at night. In the day where there is attention they can labor, and at night when there is no one the welders can weld fire hydrants shut. The tow truck drivers take apart gates and fences. Heavy debris dumped on a road that has high traffic at day and none at night would have no clear authority to fix it. Each small group operates on the scale to which they are comfortable and where they think there is the smallest risk of being found.
Graffiti is a good start, and it wakes the opposition up. But to infuriate him, you must put him in a position he can not easily fight against. After all the fire and after all the floods, the next is to bulldoze the corporate franchises on the outskirts of his city. Every McDonalds is a one million franchise investment, and setting it on fire still gets the owner his investment back. You are doing him a favor. Bulldozing it at random at night is a small risk but the damage hits the right person in the pocketbook.
