Also, are you claiming that tighter airline security would have stopped 9/11?
We'll never know now will we because the politicos caved to corporate pressure claiming tighter security would impact their already faltering businesses.
They were going to get tough in '96, they knew it was a problem:
They backed off, the problem didn't.
Freedom is nice, but without life, the liberty and pursuit of happiness part is kind of meaningless!
For instance, I sure wouldn't want to sit around for weeks or even months in a permanent blackout because hackers weren't stopped from bringing the grid down because of political pressure. Nor would I want the banking or finance system to crash with a push from hackers as it's already on tilt. Having the freedom to sit in the dark house with no internet, no TV, no radio, no money, no food, no fresh water, no working bathroom, now that would be a real treat.
Not that stiffer security legislation can necessarily stop anything, but softer security legislation certainly won't do as much as stiffer would, so if you're going to waste your time implementing security laws, go for the max IMO.
Trust me, there probably wouldn't be botnets nor spam/phishing originating from, or delivered to, any US computers if I had a pen in some legislation as I firmly believe it can be quashed!
Problem is, the ISPs need a major shove to force them to install the technology to stop the garbage as they appear to be unwilling to tackle it without pressure because of the costs involved, same excuses made regarding airline security.
