I agree. Based on the description of the incident in that news report, while the two journalists were clearly trespassing, the security guards went to far in attempting to detain them after they had left Tesla property (which I assume they did when they turned around and went through the fence). The guards should have simply noted the license plate number from a distance and taken photos of the journalists on Tesla property. And the guards should have body cams.This has been my point since the beginning. They demonstrated provocative, aggressive behavior. There was no reason for them to try to detain the journalists or prevent their escape. Leave that to the police. They could describe the car, they knew their employer, and very likely had it on CCTV.
Of course the journalists broke the law by trespassing and it appears one of them assaulted one of the guards with the vehicle. They deserve to be prosecuted for that.
Both sides acted stupidly, all because of some photos taken from a distance of a big building. The journalists caused the problem by trespassing and the guards escalated the situation in an irresponsible manner.
