Thanks Trump!
WTF does this have to do with Trump?
Some people spend a lot of money on tires and rims, and view their vehicles as an expression of who they are in a sense. Powerful, sleek, stylish, NEAT, ORDERLY....I can see where people would be pissed off about markings being put on their vehicles they worked hard to attain, and spend their hard earned cash keeping them clean and looking nice.
TBH though, I never even knew "chalking" was a thing. Never seen parking LE do that here.
