The question one needs to ask is...
How would you feel & what would you do if your home or car was selected during the night and defaced or marked without your permission?
Would this not be considered a crime? ... a collapse of our civilization as @onceuponatime clearly indicates.
Would you like that? Is this the type of world we wish to live in?

Hats off to @onceuponatime & the "heroes" (including Christoforos) who remind us all that actions speak louder than words!
