The only silver lining, if you can call it that, is that the shooter targeted only TSA workers. Had he gone after passengers as well, far more people would have died. Yes, TSA workers are there only to check passengers, but in today’s world all bases need to be covered. There is no excuse for not having someone right next to the slain TSA agent who was unarmed. Security officials need to reexamine their policies and allow for one specially trained TSA agent with a concealed firearm and a bulletproof vest in all terminals.
