I will be teaching an ESI Bomb class next week, we will be concentrating on blasts used to kill specific people. This is a picture of NY Police searching for other bombs after the initial NY City bomb last month. Bombers like to use trash cans to hide explosives, it looks fairly normal to put a box or bag in a trash can, at this moment everything in that trash bin looks suspect to this officer. In EP work we really do not want to be in the situation this officer is in. We try and empty trash cans and if possible remove them from the area, clearing the area of any suspect items or things that could hide suspect items, is the best way to stay safer.
