The mall cop rolled up his/her sleeves so that he/she could show off his/her tattoos to everybody and said to the group that they all must have a death wish if they're still standing there at the mall trying to get in, and that nobody goes in his/her mall since he/she knows what's best for everybody's life and health. The extreme poser was sending everybody home.

The mall cop rolled up his/her sleeves so that he/she could show off his her tattoos (and power) to everybody in the group, and told them they must have a death wish by being there at the mall, since nobody was allowed in his/her mall after 5 PM. The extreme poser got off on kicking people out of public places.
