So I am reading a blog on a TSA site, which describes though not in great detail the standard operating procedure for the inspection of the bags including an automated system that triggers the bag inspection. So if the inspection is warranted a human being will pull your bag and do a manual inspection and finds the notice inside the bag.
Now here is where it would get rather interesting. Since this inspection usually only occurs once during your travels unless you have to pick up your luggage and re-check it in the thought process is potentially two fold:
- Check the tag on the bag so may be this one was inspected elsewhere.
- This guy is trying to beat the system since he just checked the bag in for the flight so he might have something to hide.
And given the beating TSA has received over placing the notices into bags that have not been screened I would assume that you're going to be more likely to receive a body cavity search with placing a notice inside the bag rather then just leaving the bag as is.
P.S. Personally I would not buy anything particularly expensive to worry about it being damaged since it's more likely to get damaged if it falls off a loader. Plus please review the questions on this site related to Luggage
