What about emergency response teams, paramedics, fire departments, police forces, local and state and university, dispatchers, event planners, marathon runners, spectators, office workers in the buildings, all the media organizations (CNN, ABC, NBC, CBS, FOX, newspapers, magazines), investigative reporters, residents in Watertown, gas station owners where the hijacked man escaped, insurance companies, the boat owner, your supposed crisis actors, hospital personnel, the wounded, mortuaries and funeral planners, funeral attendees...
Let's assume it was just the 1st bomb that was staged to account for the 'real victims', I haven't seen proof of that but many claim they exist.. the last 100 meters to the finish line was reserved for VIP's and invited guests, that takes away concerns of spectators being too close to get better footage of what's taking place behind the barrier. The first responders probably aren't real police or paramedics, an example of that is the Craft International guys who were dressed as police at Sandy Hook. If you take a look at the most played video of the event, the camera man just doesn't seem to want to pan down below the fence line - it seemed too consistent to be simply bad camera work.
The vast majority of media organisations are owned by a small number of Jews who are in bed with the government - they get fed exactly what they are to report on, notice the only reporting of the marathon runner saying that they announced that they were running a drill was a local station.
Hospital personnel, well the FBI could have easily come in and said that they're taking over a section but that may not needed since it was an Israeli hospital.
The same goes for any co-ordination of the hunt for them, which reminds me - I listened to a police scanner recording, someone said that they're firing rubber bullets - another guy came on sounding annoyed that was mentioned and said to switch to the other channel, hmmm.
The funerals were private - despite all the community support.
I don't want to address all you've listed, it takes too long but I think it can all be explained without too much of a stretch.
here's another odd scene for you viewing pleasure:
