Seriously, How Many Damn People Filmed JFK's Death?

My friend's been showing me a bunch of rarely seen JFK assassination footage from all sorts of cameras. Damn thing was caught on camera by almost as many people who filmed Flight 175 strikes.

(including zapruder, thats 13 people who filmed it, that weve seen. Not including all the other footage that day, including before the assassination and minutes after, photographs, ect)
So question: How come we only here about the Zapruder film? And man, thats a lot of people filming color footage that day, given the time period.
Do these videos clearly show the limo deliberately slowing down, then speeding off? What can be glean from all these films?
