Reply #45: At the airport.

Checked bags—including those containing firearms—will then be screened for explosives by various means. Depending on the airport, methods may include high-tech "sniffers" that analyze chemical vapors, X-ray machines, trained bomb detection dogs or a combination of these systems. Not all of these methods can differentiate explosives from the gunpowder residues on a fired gun or in loaded ammunition.

If the screening detects explosive materials other than those associated with ammunition, or if screeners can`t determine the exact nature of the alarm, and if all means available (such as X-rays) cannot rule out the possible presence of explosives, TSA screeners, working with airline representatives, will make every effort to contact the passenger so that the passenger can supply the key or combination to open the case, eliminating the need to break locks.

Amtrak has dogs to check for explosives, but none of the other equipment and personnel that are provided at taxpayer expense for the airlines.

If Congress is willing to provide the funds so that Amtrak can provide the same ability to handle ammunition without the risk of not being able to differentiate it from a locked bad with a bomb, I'm cool with that. But it is not 1950.
