I read a recommendation on
Inspector Gadget this week about a pommy show called
Coppers. I've watched 4 out of 5 episodes so far - it's excellent. Far removed from your usual reality cop shows. The first episode is a corker for anyone interested in how the underclass is progressing these days. The travails of two very stupid crims made up most of the episode. It's awful, but it just has to be watched. Here's the bloke - a heroin addict who after 15 months in prison, re-offends on his first day out. This is him at age 32 (I think).
He'd been arrested over 50 times - here he is around 23.

The same effects were evident on his partner, the other crim. She was 30 going on 45, an addict and a prostitute.
One hilarious scene is where the bloke goes nuts because his partner - the prostitute - had shacked up with another bloke when he was in prison. He was quite happy to get her to have sex with other men for money, but not for pleasure.
The worst bit was the interviews with the grandfather of the female crim - listening to him describe how she started using heroin at about 15, and then went downhill from there. Interestingly, no sign is ever seen of her mother or father - just her grandfather, who clearly looks after her and loves her. It was just terrible watching what she put him through.
Each episode is about 45 minutes. Spend a bit of time and have a look at them.
As for the big question - what the fuck do we do with these people? The show doesn't pretend to have any answers, and neither do the coppers involved. I'll take the wisest course and stay well away from trying to answer it as well. Just watch the shows, and be horrified and amazed and appalled.
