Okay, so we non-liberals are happy about the man killed by Air marshals, well, maybe happy isn't the word, but I will not mourn the loss. We set up a system for counter terrorism and it worked. Sorry the guy was off his meds, but then don't fly, drive. Finally a clear mark that 9-11 measures are working. No more flights downed in Pennsylvania fields because passengers had the balls to do the right thing. Let's face it, it could have been the White House had it not been for the hero's of that fateful flight.
This is good, a step in the right direction. America should take a page out of Israel's book when it comes to air safety. No hidden guns, the protectors are there for all to see. A Glock is a pretty good deterrent. Shoot first, ask questions later. Works for me.
