To me, the most disturbing aspect of the Paris attack was the US massacre method

107. I thought the same...

... and wrote an entire piece based around it. You can read it here

I was thinking about high school shooters when I wrote,

"random acts of faceless violence are a consequence of being part of a faceless system. The system is to blame for that, itself, for making it easy (or even desirable) to achieve such gruesome 'fame'."

"...think of all those little kids who'll grow up surrounded by that atmosphere of fear and mistrust, where the only way to express anything is by whipping out a gun in a public place, and firing till you get taken down in a blaze of 'glory'."

so I reckon you're on the right track. They're definitely all part of the same dysfunctional type. The biggest difference between them is:

1) When a lone gunman shoots up a high school full of innocent teens, private gun ownership doesn't get banned

2) When a lone terrorist kills someone (or even attempts to) human rights get suspended across the country and/or martial law ensues.

That's because the lawmakers identify with person 1) and not person 2). It's also because they can earn more money by persecuting 2) and letting 1) go on unchecked.
