A club cut jersey hides a weapon very well. When I was in college, two guys got out of a pickup truck in stop-and-go traffic just north of Phoenix. They each grabbed a ballbat out of the bed and went after a cyclist who, for whatever reason, brought them some unhappiness. I don't know what happened to the cyclist but the dudes in the pickup have been dead for 42 years now. And come next year, they'll still be dead.
