Why is the camera shaking? And look how fast the clerk reacts when the crook pulls the gun. Something about this doesn’t seem right.
The orientation of the video is like a cell phone held vertically, not like a typical 4:3 or 16:9 surveillance camera.
If you look closely, someone recorded the playback that was showing on another computer screen. Probably the only way to make a postable version from the security footage on the computer. Seems perfectly legit to me.
I’m guessing that the store owners, who supposedly originally posted this, shot it with a cell phone off their surveillance monitor instead of figuring out how to digitally convert and upload the footage from tape.
