The guy wasn't a pedestrian, he was involved in the incident, he was in the vehicle which was pulled over, and thus under police control, he definitely should have complied with orders to get off the phone. The LEO definitely went over board , by a mile, in making him do so.
The city claims the cameras are operated by automation. I have seen no evidence to suggest they are lying.
how could a program know when to move away and when to move back?
Programming a camera to zoom in on an LEO would be a simple matter. Install an RFID on police uniforms that emits radio instructions for the camera to zoom in on X GPS coordinates when the RFIDs came within a certain distance from the camera. After that it would just be a matter of programming the camera to focus so long on the incident then pan out to get a broader view for so long, and then to zoom back in on the RFID.
It's just a matter of whether you want to believe it's a coincidence that it happened the way it did. Given the lack of evidence to suggest a pattern, I will say yes. Show me several instances where the timing is so unusual and I will believe otherwise.
Seriously, I have a fairly inexpensive security camera setup on my property and I could program them to do exactly that, Im sure the PD could do it as well.
No opinion on the fact that the innocent bystander was actually a passenger in the car?
