When you get both of your legs broken by a pregnant woman you just robbed, maybe it's time for you to hang up the career criminal racket. Granted she studied a bit of kickboxing, but still. Vaughn Matthews thought he found an easy target and his legs paid the price.
Good thing this wasn't Texas -- someone would have found a good excuse to justifiably "center mass" a Negro.
And good thing this guy wasn't packing a knife or a gun. Things could have gone much, much worse for this woman.
