I am sorry for your Son's experience at the border. These are troubling times, but that's no excuse for heavy handed behaviour.
It happens the other way, as my Wife's experience as a J scholar travelling back to the US demonstrated on several occasions.
There is an old adage about "give them a little power" - some people get into over the top behaviour.
