Unfortunately most who refuse to wear a seatbelt refuse to do so out of arrogance. "It won't happen to me" attitude. Funny enough my brother who both refuses to wear seatbelts and doesn't wear a helmet while riding his motorcycle almost died because someone else hit him. The lesson to learn is that it's not you that gets to decide if you crash or not everyone else gets a vote too.

Went through my local airport and forgot my 3.5 inch folding knife in my bag. Got all the way through security and to my destination before realizing. This is a brand new airport with the newest X-ray scanners. The TSA is not effective. I have a theory to why it wasn't flagged specifically that it was not a pointed knife and it was touching other metal items that probably changed the shape seen on the X-ray.
