It's almost like they're put on the monuments from before the alleged vandalism, perhaps to protect the stone from further erosion. Like plastic wrappers on a couch. There's even one put up that haven't been sprayed on, BELOW one which is. The false flaggers put up a card board at knees high but were to lazy to bend down to vandalise it.

It's also a bit unfortunate the false flaggers put up protection yet managed to miss some of the protective plates and hit the stone itself. Such dumb assess.

Also, the plates look to be eternit which was popular in the 70's and 80's. It would chronologically fit with an old grave having its tomb stone erode over a hundred years and the family caretakers in the 70's deciding to cover it up rather than renovate it.

Edit: on second inspection, all of the "cardboard" has cracks in it, particularly the left one which has a triangle piece missing. Get the fuck outta here with this low effort grassroots propaganda.
