The motivation is to destroy things that give pleasure to other people. The POS who did it probably thought (and still thinks) it’s funny. I’m sure he’ll get a stern talking to if found guilty. After all it’s not like he did something serious like video Muslims raping a woman. This reminds me of the three rock throwers in Colorado who killed a woman. One of them “liked to cause chaos”. Unlike the UK there is a reasonable chance in Colorado they will get some serious jail time.
“...a stern talking to if found guilty...”
I know you were being sarcastic, but that reminded me of the one and only time I was in England. My host was driving me on a toll road and we pulled up to the booth. He handed her cash. The lady in the booth (in a very even tone) said something like, “Dear, you know this is a charge card lane, do you not?”
We pulled out of there, and he was really upset. I asked him what was wrong, and he went on and on about how she’d “dressed him down”... Wow.
