How Safe Are U.S. Diplomats?

Police in South Korea are continuing their investigation of the anti-U.S. activist they say slashed Mark Lippert, the U.S. ambassador to South Korea. A major focus of that investigation is security and whether mistakes were made that could have prevented the attack.

It's not confirmed how many guards Lippert had with him when he was attacked at a downtown venue in Seoul, but the number of guards is believed to be small, with no requested assistance from South Korean police.
