Can the BLM organization be sued for the destruction caused by their organization?

Sadly no. That's part of the "folly" of this so-called "movement". It's a hashtag not really a movement. I'm surprised someone hasnt tried to copyright the phrase. Additionally, you know who pays for all this destruction...wait for it...wait...YES! US! The city workers who have to clean it up and erase the paint, shovel the sh*t, etc. But see, that only effects someone who works and pays taxes, etc. If your some "activist" living w/your parents or getting a "grant" to go to college (again - your welcome) you have absolutely no vested interest in anything - your just a user of a system your trying to tear down. The more this goes on, the more absurd it becomes....
