If they are this angry today, on full bellies, imagine their actions a few days or weeks after the power goes out for a prolonged period, and the supermarkets, gas stations, ATMs and EBT cards are all empty, looted, or flashing zeroes.
Oh, yeah.... I've seen them destroy classrooms, bathrooms, everything they can get their hands on - including the computer that they fought to get time on. The drive to destroy and the anger override everything else.
After it's over, then they might sit and whine that they broke their favorite toy, but for the main part they just think it's funny.
When they are starving, it'll be exponentially worse.
