Did FEMA help.....oh yes, "everyone" knows that FEMA "staged" the Boston bombings with actors and fake blood (yes there are people who really believe that's what happened)
Regarding the BM bombing you might read this little item from the local Boston media, “Police response training planned, but bombs hit first”, http://www.bostonglobe.com/metro/2013/06/07/before-police-could-plan-for-terrorist-attack-real-thing-happened/ufxjb9O0RXyzVZNPFyGkiI/story.html
Evidently just as happened with the 911, London and Sandy Hook terror episodes the authorities were running a terror-attack training program at the same time the ‘real’ attack happened, oops but you saw it all on TV so it must be real right?
