Perhaps. Perhaps it's something that can be counseled. Locking people up or imposing death penalties isn't how we are going to improve our societies. I don't doubt this happens, and I don't proclaim to have the perfect answer, but really, it's like the people who condone abortion because of rape babies. They make up what, 1% or 2% of all cases? Arguing for the radical exception is not an adequate argument against making improvements in my opinion. Maybe you should get better security, instead of better law enforcement. That's how insurance works. They don't try to pay out more money in claims, that's unprofitable. They try to mitigate or manage risk, to reduce it so that very few claims (burglaries) occur. Whether it is getting better and cheaper security systems, better means of tracking and securing valuables etc. The idea is to make it harder to be a burglar in the first place. Make it less profitable. Indeed, the world is not perfect. There will always be violence and crime. That doesn't mean we should just do more of what doesn't work, instead of trying to find ways to achieve less violence and crime. If you don't address the cause, you will just fill the prisons and increase the burden of taxes and on civil liberties by ramping up the police state. That won't make anyone safer, happier or more prosperous.
Sure, that's an emotional reaction. But looking at the situation critically, getting his just desserts doesn't necessarily undo the crime. In my opinion, a rational society should be trying to reduce crimes, not increase punishments or curtail liberties by creating massive enforcement (read, ex post facto punishment) regimes. I've always said, if you want to eliminate crime and make everyone safe, the government could lock all of us, innocent and guilty alike into 4 foot square concrete cells miles underground. Now that's a solution!
Exactly, then in turn the government will crack down on knives even more. Then the media will do the same thing to something else.
It's a bad cycle, young people are dumb, see others carrying knifes, think they'll carry one themselves to be cool or for self defense. But just having a weapon on them likely increases there chance of being injured in an attack by quite a bit. Reminds me of the old Johnny Cash song "dont take your guns to town".
