If the Sheriff's Dept were smart/cool they'd have stuck an officer in the pit themselves and posted the picture on Twitter so everyone knows it's been taken care of. It's not like it's inaccessible. The construction guys are down there every day.
Settle down. It's way more likely someone gets killed in a car wreck in the way there, or hit by a car.
I think everyone understands it's a joke. A chemically enhanced dude fell in there before the joke even started, can't control that.
