Ahh good, this gives me the opportunity to go into more detail.
I was rereading some accounts of 9/11 recently in light of the recent anniversary. And I was just amazed that passengers let their plane get hijacked. The people on Flight 93 were the only ones to get it right. The people on flight 93 didn't have guns, but the point is they didn't rely on the government to "save" them. They knew the government was not going to save them, so they took the law into their own hands.
As for the people on the other flights, they assumed the government would get them out of the situation they were in. Bad move. Never let terrorists take you prisoner. Fight to the death and kill every mf'er you can take down with you.
So your comment on the towers was silly, I was referring to people on board the planes, not the towers. Although I'll admit my argument has little to do with guns. But I'll relate it back to the topic of guns now. My overall point is not to rely on police forces for your own personal safety or the safety of your family. If someone breaks into your house, you can't rely on police to respond rapidly to a 911 call. You must defend yourself. You can't go around defenseless while criminals have guns. Now if all criminals had no guns, then of course there would be no reason for anyone to have a gun. I'd actually support the government forcibly removing all guns from every U.S. citizen and destroying them. But in the meantime, as long as the bad guys have guns, so then, will I. I recommend everyone have a gun, and teach their kids how to use them.
