These ammosexuals prance around in the pucker brush, shoot their paintball guns, stroke the barrels of their guns,m and practice their "drop, roll, and fire" as if they're therefore proven to be real men. One word describes them - pathetic.
Also don't forget the bottles of water or liquids over 4 ounces or Swiss army knives or nail files. And it is not just the airports, it is also amusement parks and stadiums where bags are searched. I attended a Bruins game in Boston and forgot that I had my nice Leatherman multi-tool on me and had to give it up because I could not return it to my car which was miles away. But as far as schools are concerned, the answer is to do nothing or arm the teachers.
