Airline Security

So, upon leaving the Salt Lake Airport to return back to the Bay area, I spent some time in the line waiting to go through security. At Salt Lake, they have an actual person who walks through the line and yells things that you can and cannot have. When you listen for 10 or 15 minutes, you hear some new things as the lady gets bored. You cannot take lip gloss or mascara through the line- they have to be placed in the little zip lock bag. And take off your watches and belts- Salt Lake has one of the most advanced security systems in the nation- even if you made it through the line in Denver, you won't make it here. I actually find that somewhat disturbing- if "national security" is such a priority, why don't they have the same equipment everywhere to prevent "leaks"? But the ultimate disturbance is that the lady said that they now allow LIGHTERS through security. LIGHTERS!?! You can't take lip gloss (without putting it in the bag) but you can have a lighter. Why don't they just provide lighters in the smoking sections for those who want to? It seems to me much more hazardous to have, but then again, I'm not in the business of national security- I only wait in the line.
