Luanda, Angola, 1998
Attempted murder 5 minutes from the cities only 5 star hotel (Presidental Meridian), on the major boulevard. Murder for murders sake (race based I bet), not robbery. Police did NOTHING.
Oceaneering failed to warn personnel of the dangers of walking on the beach in the tourist area ( I spent 2 weeks there waiting for my hitch to begin. The beach is known to contain medical waste (HIV contaminated needles) since the hospitals routinely disposed in that fashion.
