it happened with all 3 characters. it also happened with regular pedestrians and not cops. They made the AI (in general, not just cops) really nonsensical and hostile versus previous iterations. People would just drop their coffees on the ground if you stood near them too long. Also the physics got worse between 4 and 5. Probably to accommodate the bigger map? I don't know why. I wish it was them depicting racism, but that might be giving them too much credit. Especially since GTA V for the most part has a sort nihilistic philosophy that isn't social-justice oriented at all.
