And the 'trigger' seems to have been the fact the arresting officer is Jewish. He was drunk, in a boat load of trouble, and being an anti-Semite, he just let his invective fly when discovering the arresting officer was Jewish. In his anti-Semitic world view, the idea that a Jew could bring him down a couple of notches must have been rather infuriating.

Especially since other officers had given him a free pass and get out of jail free card for speeding in the same area.

And then, there is that fact he 'owned' Malibu.
