Still not hearing an answer here.
Here's another question: do you not find it ironic that the argument for gun ownership hinges on the idea that Americans should be able to protect themselves?
Unless that protection comes in the form of actionable intelligence that somebody is a terrorist threat attempting to purchase guns and/or explosives?
So what you're really doing is forcing the idea that the only self-defense Americans are entitled to regarding terrorism is owning a gun, on the astronomical chance that somebody will be able to identify the terrorist--remember, the intelligence is out--and like shoot them before they can do anything with those guns and/or explosives?
That's the plan huh?
