@ehBeth,
It's not done at all either in Australia.
It's called Innocent until proved Guilty and therefore, the person is protected to the best of our ability until that point in time.
On a side note.. Youth... will always test the boundries and do wrong, the laws in those days weren't as rich and the police weren't really around and if they were it was like, look straight ahead keep driving... I am guilty of doing that alot as a teenager, early 20's.
This guy is my age.. We catch taxi's these days, it's called being responsible.
Not withstanding, he may not have thought he was going to have too many at all and it was after 2am, consequently, evident that he'd been drinking alot by that time and possibly thought it's only a block or two I can do it, no big deal no one is really out at that time of the night... Irresponsible but possible that was his thought pattern... And he should know better at his age... But, I would say it's sad on both accounts. His, with his non rational thinking due to alcohol and what he has to live with for the rest of his life and sad for the person who died, for being out riding somewhere, trying to get somewhere, after 2am in the morning and that in those last moments, he more than likely heard the car drive away, leaving him there.
The last part would haunt me for the rest of my life, knowing that.....
