Would putting him in jail really achieve anything apart form costing the taxpayer money?
This is the key question, tyred.
Lengthy prison sentences in tough prisons just make new criminals as far as I can see, I see no point in locking him down in the 'Scrubs or somewhere.
I do think a spell behind bars of somewhere would concentrate the minds of other car users that killing someone is killing someone.
I can see no reason for him not to go to a low security prison, where he would mix mainly with white-collar criminals - even an open Prison such as my local - Ford Prison, where you often see the lags wandering around. I doubt he's a flight risk.
The key - as mentioned by someone (sorry forgot who) is, he has demonstrated a lethality while driving and common sense suggests he should never be allowed to drive again.
Unfortunately common sense and the motor car don't seem to coincide in the courts or the people I talk to.
