Do you think maybe the fence wasn't attached in some spots and the criminal knew and went through and when the cop got there it had snapped back in place? But the fence didn't seem to be moving in the cop's headlights.
Here's what my nephew and I figured out years ago when we first found this video.....
Drive any car at a high speed into a chain-link fence...what's going to happen?
If you hit one of the support polls (that the rolls of chain-link are attached to) - and it's securely anchored into the ground, it's going to do some serious damage to your car....BUT, drive your car at a high speed into the chain-link area of the fence - avoiding the polls - and those rolls of chain-link won't stop your car, your car is going to go through the fence....the chain-link just isn't connected to the polls that strongly, so it wouldn't be the same as driving your car into a brick wall, which is sort of what this video implies...
It (the video) takes the position that the car somehow "magically" (or paranormally) passed right through the fence, but any car will do the same thing....
What must have happened is some of the connections (securing the rolls of chain-link to the polls) had to break, but not all of them, so the fence "snapped back" after the car passed through it.
