Dinner party scene

Okay so I’m just now watching Borat for the first time as I had no interest for the longest time and recently after hearing some backstory I’ve been wanting to watch it. Well it happened to go on Netflix today so I’m watching it for the first time, and I’m so confused about the cops being called at the end of the dinner party, him sh*tting in a bag and bringing it to the table was okay, but they drew the line at him bringing a black woman to dinner? 😂 there had to be an incident off camera to cause that reaction because it went from 0-100 so fast lol
