It feels like there is more celebration this time than with the sub. The sub was basically a suicide, a death as a result of arrogance.
This one on the other hand is different. It's almost certainly an instance of revenge on some level, either for a loved one or themself. And the celebration in turn seems to have responded to that.
The McDonald's execs aren't anywhere near as bad. But they ain't innocent either. They're perfectly happy to pay poverty/starvation wages. They're perfectly fine with class war.
As /u/comfy said, we already know enough. We know that cops can break encryption on your phone, get everything from your social media accounts with full cooperation of the site owners, they can track your phone even if it is off, they can track your payment methods for your ebike get away vehicle to the CVS you bought your prepaid card with cash at, they can track you with the thousands of cameras they have everywhere, they can use gait identification to ID you even if you have gloves on and a mask on, they can plaster your face all over the internet, use thermal vision drones to find you in some field.
The police are militarized and have their surveillance tentacles in every crack and crevices they can. We know this already, and there is no value that such a trial would provide for that.
It's a shitpost community, you can relax.
