EDIT: I see my post is being downvoted. I know that it may come across as insensitive to immediately leap to the gun control debate, but frankly I'm more angry than upset by this news. How many times does it have to happen? We have a good 48 hours of emotional outpouring and then everyone forgets it ever happened.
Pardon me, but I grew up in a country where 'oppressive regime' was not far off at all, and where brutal murders happened in my neighborhood all the time. I knew my Dad didn't own a gun and it scared me to death. So how dare you belittle my beliefs in the need for armed civilians. Disagree with them, by all means, but do you really think I'm arguing children should be murdered en masse?
What you're proposing is, in my opinion, that same thing as arguing that the government should regulate or perhaps even ban internet access because of all the child pornography. Screw civil liberties, think of the children!
edit: Also, I would argue that confiscating laptops at airports will save as many lives as trying to ban guns in the US at this point.
edit: In case it wasn't clear, I don't actually believe the South African government was doing what it claimed - but believe when I tell you we had no idea just how bad the government was until after it was all over. My point was that safeguards aren't always what you think they are, and they they won't always be there. You can't decide to give citizens rights only when the government decides they need them.
