Our "other" recent jailbird ex player, Adam Chapman, served longer than this for causing death by dangerous driving. Whilst you can't condone what Chapman did, I'm pretty sure he didn't set out to kill anyone and there was an element of "accident" to what happened. Thompson held his victim hostage for a couple of days, so it was very much a decisive action and premeditated. For him to be out this soon, the law really does let us down sometimes.
