hmm so maybe it went like this:
old guy, crossing a road, not really thinking much, used to being allowed to cross the road wherever he is, knew vaguely about jaywalking but didnt know how much trouble it could cause or just wasnt thinking about that, maybe he had a cool research idea about growing ears on the backs of pigs or something.
Old guys viewpoint: some random guy in a weird outfit he didnt associate with police (there wasnt a tit-shaped helmet on his head) tackles him and starts to pull him around. He struggles, he's alarmed, doesnt know what's happening, suddenly the pig-with-an-ear-on-it's-back idea is lost. The other guy calls for assistance and five men are on top of him, then he realises, hey maybe these guys are cops, crikey they're being a bit rough arent they? i'm pissed.... grrr
cops point of view: There's nothing to do and i have no donuts.... Maybe i can arrest someone... i'll keep an extra good eye out for misdoings and make an example of someone. I discovered i had erectile dysfunction last night and i need to show i am still a man. WOW there's a misdemeanour right there... that guy's jaywalking. I'll arrest him. Grabs the guys arm, guy jerks violently away, cop realises the guy might resist, pins him down, guy struggles, surprises cop with his strength, cop gets nervous that he might be seen to be unmanly, calls for a assistance ina deep manly voice, his friends drop their donuts and jump on him, guy seems to get very angry, maybe he is resisting arrest cos he has drugs on his person or something? better be strong with this guy....
