someone has raped your sister what do you do?
call the cops?
find said rapist scum. take a crow bar to his knees, ribs, and arms. than take out your handy dandy buck knife. or if you are less brutal and are good friends with a tattoo artist or are one your self. you the option to tattoo or carve 'rapist' into/onto his forehead. now drop him off in the most gang infested area of your city. don't worry he can't run that far. you shattered his knee caps, remember? and you are now free to let your imagination run wild.
