All this does is further disarm the populace and makes it even easier to carry out an attack. Australia or New Zealand could have an attack like this happen tomorrow, it's not like they are able to keep handguns and drugs away from your normal criminal gang member there, let alone a determined terrorist.

"All this does is further disarm the populace and makes it even easier to carry out an attack."

If the majority of school shootings etc in the States we're stopped by the populace with guns then yeah I'd agree with you.

Of course not. That's a tautology.

It may reduce the frequency and effectiveness of such attacks, as Australia's tightening of gun laws did for shootings. I'll take it.
