First hand knowledge
So just to be clear on the consequences of violent assault:
My stepdaughter's 16 year old boyfriend was beaten up and kicked in the head. Several days in hospital and a head like a watermelon.
At 18 he started to have motor problems and was diagnosed as having neurological damage.
At 20 he has MS, 'probably brought on by the trauma of the blows to the head'.
At 22 he's permanently in a wheelchair and unable to fully function.
And did I mention he was a very bright student with a good career ahead of him?
So that's effectively someone's life taken for a kick in the head.
