Could you supply a name of the woman or link to this event? Or is this first hand knowledge? Did your see this happen?
IMO, Her son is dead because he was called upon to fight a war against terrorism. He answered that call, and now has given the ultimate sacrifice. A mother's grief is truly heart wrenching, but she chose the wrong place to demonstrate it. Congressional inquiries would have been a better way to go about it, imo.
The President did not kill her son- lawless criminals did.
