The 4:30am tidbit creates a contradiction here.
The news article calls him a 'former Marine' but he's apparently buying a 6-pack of Bud at 4:30am. Combined with the educational beat down he delivered, this clearly indicates he is absolutely still a Marine, even if he is not currently serving.
As a Soldier, I've noticed amongst my Marine cousins that once that switch in their heads is set to 'Marine' that shit never really switches off, and that is overwhelmingly a good thing.
