There’s no need to indulge in conspiratorial thinking, here. Whatever you think of Mangione’s motives, it seems overwhelmingly likely that he did it and, if so, he will almost certainly be in jail for the rest of his life. There’s no need for them to do anything else to him. It seems as though he acted alone, so a broader anti-terrorist crackdown is possible but unlikely, and even less likely to be effective.

As for the CEOs, I imagine a lot more money is going to be spent on security and they’ll probably demand the businesses they work for pay for that, which actually seems fair, as far as it goes.

While I don’t have any sympathy for the Republicans, they didn’t seem to even consider more gun control even after Trump was actually hit by a would-be assassin’s bullet, so I doubt they will now. They might pass a law against 3D gun printing, but it’s not even slightly enforceable; I believe owning such a weapon is already illegal but, as Mangione has demonstrated, there’s not much to stop someone making or using one.
