Terrorist-enabling attitudes?

It's not the job of the government to keep us safe from every single criminal. If we would just stop expecting the government to do that, and rely more on each other and our second amendment rights, we could get a lot more done and be a lot less afraid. A "classic" terrorist tactic that has been used in several conflicts has been to attack innocent people and even law enforcement and government offices to impress people that "the government can't keep them safe" and therefore reduce the government's credibility and eventually topple the government. That tactic works like a charm when both the government and the people let themselves be persuaded that a government is expected to "control the security situation". But it's not true!! The underwear bomber of last year succeeded in terrorism without causing physical damage because he caused many people to panic, he caused us to spend a lot of money on answering his specific tactic, and he caused our media to publish great morale boosting stories for the other terrorists. If we just take a different attitude about it the terrorists would be a lot less effective. Underwear bombing is shameful for a lot of reasons :) We have to say "Hey, this guy was a crazy idiot and a shame for all Muslims" and then change nothing because our security measures did work to prevent other things he might have tried and our new "kill 'em so they don't crash our plane" posture worked too. So just continue on with our lives. Yes, eventually the terrorists will kill someone again... but American criminals are killing people every day and we don't spend millions of dollars every time a murder happens.
