The NRA and the like will probably use this again as an opportunity to demand even more and even bigger weapons for the police, the Secret Service and everyone else. Not that it will do any good, but they'll try anyway, I suppose.
You see, the problem wasn’t that the agents didn’t follow through on tips from the public, or have a marksman on the highest available rooftop for surveillance and counter sniping. No, the issue was that the agents could not simply shoot through the building to get the shooter.
That’s why they need recoiless rifles for the agents
But... but he's not a hurricane... I guess they could fix him up with horse tranquilliser and bleach afterwards though. (adding a /s here for the terminally oblivious)
Why not arm everyone in the crown. Good guy with a gun and all. Or, just call it democracy via bullet, that's what they want anyway. Just let the mob shoot it out at every rally.
