Those 50 some police did not resign from being police. They resigned from emergency response duties because they were shown that their dept will not support them.
There is also more to that “poor 75yo man” story. He is a professional agitator with a now-deleted social media history of hating the police, despite this hatred he showed up hours early before police did with a police motorcycle helmet he wanted to return because it was the right thing to do, this stated by a Buffalo/NPR reporter who he happened to be there with, while BLM activists knew/recognized him as an agitator and told him to go home, asking him why he was there and replied a few times “just for fun”, then in the full video you can see he is using he is using his phone to scan over police radios (supposedly to skim Bluetooth advertising addresses and RSSI correlation, to get someone information to listen in on private band police traffic), all of this while not wearing a mask up until the interaction with police when suddenly he has “two” masks, one which appears mouth guard of some sorts with a mask over that.
But whatever... it’s a lot easier to just say the police beat this guy (pushed him back from an advancing police line)
