I suppose props would be available through the usual purveyors1), provided the producers made clear what the props were meant for. IIRC, freedom of the arts comes with some leeway regarding the use of verfassungsfeindliche Symbole.

Fun fact: when Ribbentrop went to Moscow in August 1939 to sell Stalin a crate of Henkell trocken sign the “German–Soviet Non-aggression Pact”, Soviet protocol had to use all the props Mosfilm was using at the time producing a big anti-fascistic film to give him a proper diplomatic reception.

Not really. The Luxor Temple desecration in 2013 was a Chinese tourist, the Sedona case a couple of years ago was actress Vanessa Hudgens, and monument desecration in India has become such a problem that it is becoming part of the school curriculum. We get a fair bit of vandalism on sites here in Hawaii, and generally don’t know who did it. I think it is just a matter of who has the resources for being a tourist in areas with such sites. (The English during Empire were notorious for it.)
