Men In Black

Excerpt from Nick Redferns Men in Black lecture.
For me, no less interesting part of the UFO phenomena are the men in blck. I know very little about them, but Nick Redfern with his wealth of infomation has certainly tickled my curiosity.

While he was talking - two thoughts crossed my mind - the first was that men in black were, as he said, government agents trying to hush up the witnesses (for reasons I cannot understand) and the second is that men in black could maybe be aliens who are disguised as people …. this sounds completely insane, and as I write it, it seems less and less probable - why would they do that?

What do you think?
