Knitting needles at your discretion
I find it incredibly ridiculous that the TSA website states that knitting needles are allowed, but at the discretion of the screener, may be determined to be a weapon. They’re either a weapon or they’re not. Knitting needles may or may not be dangerous, but they are NOT the problem and I resent having to worry about whether the TSA screener in question is having a bad day in determining whether I’m going to have anything to do on my flight tomorrow.
If the regulations really served a security purpose, you’d think they could some up with some sort of objective standard.
