Not sure what law you broke but:
If you entered this country as an illegal alien, don't worry, just go to Cambridge or San Fran, they don't enforce the law
If you raped a child with a hot curling iron, just donate to Martha Coakley's senate race and she'll ignore the crime
If your last name is Kennedy and you drove drunk off a bridge and left your female passenger to drown, you'll be elected Senator someday.
If you failed a breathalizer, just tell them it was the toothpaste.
If you might be convicted of a felony and are the Speaker of the House, just cop a plea and they will give you a morning drive show.
If you shot a criminal who was trying to stab you to death to steal your ipod, your F**ked. Self-help is unacceptable.
