Ok. So lets say that is the case, he is just so lazy he doesn't want to work and doesn't want to deal with the situation. He wants to just monitor and hopefully it all goes away so he can collect a check for doing nothing. There are people like that at every job in the world. That still would not justify that when the situation eventually involved two males, he chose to tell the one defending to back off, rather than the instigator of the entire situation, who was still instigating. One would think the first and most logical response would be "ok back off" to the actual instigator, since now this required the cop to actually have to work now. What would make one think that when he finally decided to intervene, the brother defending his sister from attacks is the bigger threat of the situation? This tends to lead to an assumption that the "most likely answer" is the cop was as ignorant as the man harassing, more than the cop was just lazy and wanted to go home.
