re: #5 Destro
Being in Benghazi with light security is what puzzles me. Benghazi is a known extremist strong hold and there was a previous attacks on western representatives there.
Amb. Stevens seems to have traveled with limited security in general, as a choice, eating dinner with local officials, attending hospital openings, etc. On the day of the attack he apparently had a five person security team with him, and the consulate had its Libyan security team.
