A gun won't do you a bit of good when they bomb your apologist ass to smithereens.
It's difficult to get ahold of explosives.
They'll probably run people over with an SUV or knife somebody in Walmart.
No it isn't. A smart 12 year old can build a bomb out of legally obtained materials reading the instructions online.
It's not that easy or we'd have a lot more of them. And a lot more that actually exploded when nutcase mass shooters rigged them up in their vehicles for the cops to find. But usually they're duds because it is not that easy to build a functioning bomb. Building bombs requires training. That's why they have Bomb Schools in the ME.
True to an extent no question. McVeigh learned his skills in the military. However, it ain't that hard to build simpler, less devastating devices. I was gonna find you a link to build a simple bomb, but that kind of search sometimes gets tracked so I'll pass. Not interested in a 3 AM visit from the FBI.
