There was a video early this month (on Twitter) where a white woman who called 911 about a black man standing on the road away from her. Her car was in between them. She was screaming down the phone, 'A black man in attacking me!!! I'm a white woman and I'm alone!!! please help me!! He's coming toward me!! Please, help!! Arrgh!!! He's got my arm!!! Please don't hurt me!!! Please come quick!!!... My arm!!!' etc. The man was just standing there, not moving towards her, the woman standing on the same spot, no one moving, and he was saying, 'I'm just asking you to move your car... wow, wow, you're really doing this'. Anyway, he kept filming until the video went off. I had shivers down my spine.
Another one I saw this morning, not the kneeling one, where a black UPS delivery man, WITH A TROLLEY OF PACKAGES! was accosted by a white woman who said he looked suspicious and rang the police, about him being black and being in her neighbourhood.
There are lots of similar videos on the internet. I said all that to say that the smartest thing a black man in America can do is to switch on his camera once an argument breaks out because the police (or neighbours) will not hesitate to shoot you down. The reason we don't see the start of the altercation is because it isn't planned. People switch on the record button when things take a turn.
FYI, last month, I set a shortcut on my phone to automatically record. I couldn't get it to auto record video but at least if I clicked the button on the side, audio will be recorded. I'm a black woman and I'm no longer taking any chances.
