alexb757 - You're quite right about security at Lagos, my experences include:
a/ arriving at the gate, one time, about 2 hours after the advertised departure time, due to a delay caused by aircraft serviceability, for an 11 hour flight. We found the entire load of passengers had boarded themselves, and were settled down aboard, with the kids running everywhere, waiting and shouting out to us that we should go now!
We had to offload the entire passenger cabin, do a really good security check, get the cabin reorganized, and reboard, which meant an extra delay on the delay!
b/ each and every bus trip to and from the airport to the hotel, about 20 minutes each way, had to be escorted by armed guards.They had loaded automatic weapons in each car, one in front and one behind, and would not stop for any traffic holdups.
Anytime there was a traffic blockage on the 'road' the front car would simply drive up between the lanes and bang on the side of the cars blocking the road, with the butts of the weapons - that usually got them moving out of the way! Not a pleasant way to travel to/from work.
I was there with AAI for several months, the best part was the layovers in NewYork, London and Dubai, otherwise I could not have lasted even that long.
Cheers
