I don't personally have proof of how quantum physics works either. Should I disbelieve that?
Was quantum physics theorized by politicians? Or by thousands of scientists publishing tens of thousands of research papers showing results of repeatable experiments? I'd assume you'd take thousands of scientists word for it because they're generally very reliable. Government officials? Not so much.
Personally, I think politicians and certain government officials should should usually be assumed to be lying until proven otherwise. Or at least their words taken with huge grains of salt & face heavy skepticism until proven otherwise, with evidence.
"We know where they (WMD's) are. They're in the area around Tikrit and Baghdad." - Donald Rumsfeld, prior to2003 Iraq invasion. Did you take his word for it at the time smallc? I'll admit i probably did...oops! Well now we have another Donald in hot water...WHERE'S THE EVIDENCE EVERYONE??
