If we are talking about the same video I have seen on the net, this was an incident of people being killed inside the homes by other people with guns. Bombs dont magically pass walls and leave the entire building unscathed except for a few holes in sheetrock inside and a pile of dead bodies. It also wans't friedly fire from the outside going in, again, these were dead people in rooms with a few bullet holes in the wall here and there, a house of occupants killed by friendly fire would have to be saturated with holes unless the entire building was made of windows, which it wasn't

I'm making no judgement as to who did it, but the people inside on the video I saw were killed at close range with firearms. The video, however, is just that: groups of dead people inside an otherwise normal home with splatters of blood and bullet holes in the wall. Could have been killed under many different circumstances, bodies could have been moved, etc etc, so I'm making no judgement other than it WAS NOT a bomb and if the crime was committed at that location (ie, the bodies not moved there) then it was definitely either intentional or extreme recklessness.
