This is a repeat of things that were happening in the 70s and 80s before Rudy became mayor - vandals graffitied and damaged subway train cars parked in fenced-in over night train yards, all the time. Very few were caught or punished.
If & when they do catch the perps who did this, I think they should get some sort of punishment that they will long remember even after a possible long sentence. Doubting anyone could get life for this, but the might remember a good caning. Yeah, I know we don’t do that here.
