I've often wondered this of Art Bell (no offense Art!), Rense, Jones, etc. The reason the "Roswell Incident" went the way that it did was so that those who managed to witness the test aircraft became unnaccountable for explaining their ongong classified projects.
Alex Jones claimed not long ago that the most recent "Bohemian Grove" protest was conducted by the military (government masquerading as protestors).
Spectre, you surprise me, everyone knows that the entire 'Roswell' incident was fabricated from a mishap from a simple 'test ballon,' this the CIA used to CREATE the entire 'UFOLOGY' movement. :-)
