Slippery Slope [Only Slightly Off-Topic]
Here in the States, the laws and times served for killing someone vary greatly by state, and by the type of murder committed. I once saw a statistic [yea, I know, liars lie etc] that said the average time served, in prison, for killing someone was six years.
I DO know that I once had a tenant in Wisconsin who had been in a bar brawl and his opponent died, I don't know what his eventual charge or sentence were, but he served eight years, then upon release a short time on parole, than he was completely free for the rest of his life. He became my tenant when he was in his sixties, and I will say that he was one of the few tenants that I could trust to pay on time and to treat me decently, as I treated all my tenants.
I believe it was in the state of Washington, back in the nineties, that they changed the law for 'sex offenders' so that upon the END of their time served, a committee would meet to decide if this person 'might offend again' and if it was decided to they MIGHT do so, that person could be kept locked up indefinitely - despite his sentence having been served in its entirety.
Of course people said "Great! They shouldn't ever get out!" not thinking that today it may be the horrible 'Sex Offenders' but next year it could become simple petty thieves, and yet later down the road, anyone who has run a red light, or been late paying child support. Its a slippery slope people!
