Prisons may not be perfect, but they are the best solution we have yet come up with.
Yup, "yet". But maybe this is the time where we actually do come up with something better. It doesn't make sense to slap a bracelet on a mentally deranged serial killer, tell him "watch it, cause we're watching you" and send him back onto the street. But doing the same with a shoplifter might actually be better than putting him behind bars for a while, having him loose contact with the real world. He may not be able to to any harm while in prison, but when he gets out, chances are he's not thinking "wow, that really taught me something. I'll never do it again."
To quote George Jung in Blow:
"Danbury wasn't a prison, it was a crime school. I got in with a Bachelor of marihuana, I got out with a Doctorate in cocaine."
As Eric Schmidt recently said: "At the moment we know roughly who you are, roughly what you care about, roughly who your friends are." And according to the article (and simple common sense), "Google would likely store more personal information about its users in the future." This new mailfiltering proves just that...
That doesn't spell much good for the future...
Backed up the system lately?
