I've been thinking about the failed airliner attack, and realizing that it's a strong argument in favor of the 2nd Amendment.
All of the intelligence, all of the security measures...and at the end of the day it was a fellow passenger on the scene that said, "not on my watch" and stopped the attack.
Now they're talking full-body scanners, so TSA can see through your clothes. I can see this generating discussion where people say "enough." At some point, people need to realize that the last line of defense against aggression is each other. Any soldier knows this. A guy on a plane willing to die for his cause has much less chance of success if he's surrounded by passengers willing to die for theirs. Ultimately, when the enemy has presented himself, it's not up to law enforcement somewhere in the distance -- it's up to us, right now, facing the concept of physical confrontation to save our lives and the lives of those around us.
It's time we shake off the cobwebs and reclaim the concepts of individual responsibility, personal liberty, and the idea that we have common interests and that we have each others backs. The Second Amendment spells it out: real security ultimately resides in the individual, not government.
