Take a look at this video - it asks some interesting questions:
It looks to me like the powers that be established the "lone shooter" theory right after the event, and then saw no need to investigate further. That sounds just like the JFK, RFK, and MLK shootings, doesn't it?
And if that's what's going on, we're just being lied to, plain and simple. There is no investigation.
When are we going to DEMAND a stop to this kind of BS?
