“He died as a consequence of his own actions. That is sad.
Was he one of the ones in the video destroying utility security cameras?”
For the sake of discussion, let’s say he was one of those who took down the security camera. That certainly doesn’t seem grounds for getting shot up. Let’s also say, as you imply, that he’s not the sharpest knife in the drawer. Traditionally, ‘slow’ people in society are given a bit of ‘extra consideration’, such as “that boy ain’t quite right in the head”, there certainly was none of that. It doesn’t matter if what (perhaps) he took down was a utility security camera, or what was possibly a camera being used in surveillance of the protestors. Is either grounds for getting shot up? I firmly think these guys chose the wrong hill, but it seems their very worst offense was taking down a security camera. It also seems his paranoia was founded.
There were many choices along the way that ended with someone getting killed. Any of the choices made differently would have changed the outcome.
This is not rocket science.
