Smart phones & Dumb Cops : why WWII revelations are history not journalism

Tiny, high resolution , sound and colour motion cameras - like those found in even the cheapest of today's smart phones, didn't exist back in WWII.

Tiny (but noisy) 8mm color motion cameras did exist then, but were rare and needed good strong summer daylight to work well. The ability to record sound and film together in one compact package simply didn't exist for another 25 years .

The closest equivalent to the Internet and YouTube back then were the newsreel firms but these handful of global firms were under firm government censorship control in peace as well as in war.

Dumb cops - like the dumb cops in the Nazi extermination camps - could get away with a whole lot of evil back then, assured that at best a few grainy black and white stills might get smuggled out.
