I saw this first hand. Years ago a suspect was approached by a male and female cop. The guy sucker punched the female, right away and knocked her out. It took two more squad cars to “subdue” (beat the crap out of) the guy. I was the lucky one that got to clean up all the blood. Reality, if it was two males, it would have been a clean arrest. Backup wouldn’t have been needed. And I wouldn’t have to clean up massive amounts of blood. Also, Slowest ambulance in Lansing, Michigan history.
