>But what exactly is enough? For the rest of the world, a couple of shootings. For USA, apparently nothing.

The right would say this wouldn't be a problem if more people had guns to defend themselves with. An idiotic argument for sure especially given the details of this current attack (32 stories up... far away, etc).

Even if this happened at an NRA rally or gun show they'd come up with some other excuse.

how about the precautionary principle?

If people aren't within weapons range of each other they can't shoot each other. So force everyone to stay a mile away from everyone else, and increase the range until the problem goes away.
