Goth clothes 'prompted killing'

Certainly civilized nations can't expect citizens to resort to violence to protect themselves, and civilized nations can't be expected to prosecute "poor misguided murderers" to the fullest extent of the law, but in certain civilized nations you risk your life walking down the street.

Quite the civilized utopia you've got running over there.

If previous experience holds true, the 15 year old that played part in the killing will probably get a few years in jail and a few on probation.

For as much time as we spend trying to figure out effective methods of (ahem) rehabilitation, the two most obvious methods aren't to be touched with a 10 foot pole. Locking them up and throwing away the key, and the journey to room temperature.
