Of course, my wife wouldn't let me, so I am a differenct variety of a candyass. I can Romper Stomp a bunch of "youths", but I cannot handle my tiny wife (To be fair, she is 100% Cuban)
A sting type operation would solve this. Hire a bunch of "soccer hooligans" to pose as feeble passengers and when the thugs climb aboard and start taunting, they give them a bit of their own medicine.
