Non-moving and hanging would probably get you a malfunctioning equipment ticket. If it's on the truck or trailer it has to function properly. What you might deem safe to operate can be a different story from the leo. Somethings you allowed to head directly to a repair facility if it doesn't affect a safe operation. Could you guarantee a bump would've finished the door off and it fell completely? If it was written up and you were sure it wasn't going anywhere I'm sure a normal officer would let you slide. But they all aren't normal. Maybe you could of tied a rope to it or strapped it to make it look good.
I worked for Central Transport before and we had a bunch of them damaged doors. We would use a forklift to open and close them. Force them up, force them down.
