What were you hoping to achieve by sending that report?
Most people would have just thought "wow, lucky I wasn't caught with that", taken it out of the bag so it didn't happen again and carried on with their lives.
Deviating from that normal response makes it look like you're just trying to cause trouble.
As I wrote in a very different thread, I avoid putting anything in baggage that I might carryon that is even marginally prohibited. I used to do a lot more travel and it's inevitable that knives and the like would inevitable get left in a pocket.
Officer: Look at this knife. You're trying to take this on the plane?
Me: Holy shit I didn't realize that was in my bag.
Officer: Well do you want it back? Or do you want to fly today?
Me: I don't want it.
Officer: Don't mind if I keep it?
Me: It's all yours.
It was a $13 knife, but he liked it.
No doubt that was a security violation, but it's all security theatre.
Still screened and detained 100 percent of the time, sometimes for hours, sometimes having to surrender personal devices, decades later.
The message is very clear.
