I guess there are those who might feel threatened when someone like me pulls out my keys to open a door because they are attached to a small, red Swiss army knife with nail file/screwdriver, scissors, plastic toothpick, and 2" knife blade. I know the size 2 hats who man the TSA security scanners are because I've lost a couple of them to their vigilant commitment to protect us as we go flying off to wherever.
IMO this is another fine example of elected lawmakers busily going about the business of 'monkey business' vs taking care of the people's business for which they were elected. I can see a resurgence of Shirley Temple and Fred Astair/Ginger Rogers movies coming soon to a theater near you.
I've carried a pocket knife my entire life and certainly don't plan on giving it up now. Besides the $$$ and the over abundance of tourists, I now have another good reason to stay in Texas and avoid spending any time or $$$ in the Aloha State.
