Shortly after I wrote the piece about the pilot video showing airport security lapses, I just read this one about a driver who apparently was able to get through a US Secret Service checkpoint. It appears that the driver was not a threat to the President but look at the pictures. The US Secret Service agent has her weapon drawn and yet the driver goes through the checkpoint anyway. The picture of her running is even more concerning. She failed to stop that vehicle. I don't know if the rules of engagement prevented her from firing or if there was some other reason she appears to not have fired. The bottom line, had this driver been intent on doing something it looks like he would have been more successful than he should have been.
This is exactly what happened in Beirut in 1983. Suicide bombers hijacked a truck and upon approaching the checkpoint gate, accelerated through the fence. The sentries did not have magazines in their rifles per the rules of engagement. The truck was able to reach the barracks area and detonated 12,00o lbs of explosives. In the attack on the American barracks, the death toll was 241 American servicemen: 220 Marines, 18 Navy Sailors, and three Army Soldiers. Have we really learned anything in the nearly 30 years since this incident?
