Not meaning to denigrate ALL women, but what you said is not true 100% of the time.  There have been cases in the U.S. mainland, plus a few locally that I'm aware of, when female officers were unable to immediately immobilize or deter a suspect from committing grievous harm primarily because of a lesser degree of physical size and strength.  There is even a notorious case in Hawaii of a female officer who proved unable, either through lack of training, the size or her hands relative to the size of her department-issued handgun, or some other unknown predisposition, to quickly shut down a violent altercation.

I'll be the first to agree with you that many male officers are physically small and possess far less strength than a random suspect they may have to deal with.  But it is also statistically inescapable that the 10% rule has held sway in Olympic-level competition for as many years as I can recall, where female physical prowess has always lagged roughly 10% behind that of males.
