JJ,  I agree, Kahn's speech was an inflamatory political speech that served its purpose quite well.  I also agree with you on Trump's response.  The mother speaking though is a little more nuanced.  That depends on just how, for a lack of a better term, devout the Khans are with their Isalmic beliefs.  For sure she would be able to speak here in the U. S. and the law would protect her if she suddenly rushed the podium to speak that night.  I also agree that the service members make the sacrifice, not the family members, though the family members pay the price of that service.  Unless the Kahns marched their son into the Virginia ROTC office and made him join ROTC, and made him complete his training, then contract to continue his training, and then accept his active duty commission, CPT Kahn made his own decision to become an active duty officer and serve his country.  The Kahns suffered a heart wrenching loss but I seriously doubt they sacrificed their son.
