Ummm. Not exactly. A smaller male can almost always defeat a larger female. Weight alone is not an indicator. The norm for percentage of body fat for women is 20-30%. For men, it's 10-20%. Women are carrying around more fat than men, which does nothing for their strength or stamina.
Your examples of a 5'2" policeman vs. a 5'7" police woman is unrealistic. Nobody of such short stature should be a police officer. We cannot have policemen the size of 13 year old girls.
130 pounders belong in the ballet, not in law enforcement - male or female.
The more of these ballerinas we have in law enforcement, the more thugs will be tempted to take a swat at them.
Each week we read in the papers of a thug disarming a practically helpless lady cop. When will we stop this PC madness? Or like in this article, everyone is surprised that a lady cop got hurt. Duh! Don't put ladies in uniform, and they won't get hurt.
Just as girls do not belong on the football team with the boys, ladies do not belong on the beat. If they do, nobody should be surprised when they get beat or killed.
