I used to maintain a blog of arrests of TSA officers and baggage handlers. At its peak, there were on average 2 arrests/week for stealing from passengers. It’s actually gotten better (less theft) over the past few years. I no longer keep the blog, but it’s down to about 1 a month.
I think the TSA has made us less safe. If there are so many people desperate for money, what’s stopping them from accepting a payment to get something through?
