You say these people have been caught in lies... what lies are you talking about? and where is the proof that they are lies
Just as some examples:
Schneider for instance, stated his father was a U-Boat commander in WW2. This is a lie. The simple answer to this one is that there was no U-boat
commander in WWII with that name. Only 2 commanders with that last name in the war; Herbert Schneider died while in command of U-522 and Manfred
Schneider only commander the small XXIII boat U-4706 for the last 3 months of the war, never on patrol. This story is just that, a story
He claims his cancer was caused by an ET weapon shot to the chest, yet the cancer was in his arm, not his chest, for starters, plus, his line of work
exposed him to the cobalt radiation he claims was due to the "weapon".
The other issues are similar to issues with other claimed Dulce proponents. Namely, their details don't match (they are barely even similar, except
for feeding off each other). There's a great thread here on ATS about Schneider, that goes into many other details.
Cooper is a complete nutter and paranoid who ended up getting killed in a police shootout. He made so many predictions of attacks, etc. that never
came true, that there are even tons of videos out there on the web that detail where he was caught in lies. Simply Google on Bill Cooper fraud, and
you'll find plenty.
