Ability of film to withstand image destruction?

Overall, it sounds like processed film, especially a B&W negative, is extremely robust. That's pretty good to my way of thinking.

That didn't stop various political leaders from erasing people from the visual record when it suited them, long before Photoshop!

Wow, that's a crazy link. I looked at them all...makes me sick. No wonder average folks seem to place very little value on photography. May as well be a graffiti artist with a spray can...
