Cop(s) blocking

[SO•Sebas]

I don't see why this would be prohibited as it's not using force. The cop simply closes the door on the possibility that a suspect would flee the scene.

IIRC, there was once something "implied" in the rules that if it was clear that the suspect would be trying to escape/flee, the cop didn't have to wait 45 seconds to use "force" in the chase. Not sure where I saw that though.
