Does this also mean that of 100 randomly selected people (of whom an ordinary proportion are cops), that about 20 of them have been or will be in an abusive relationship?

I don't mean to downplay the 40 number in the police case (which is very high and kind of terrifying), but, 20% is still a lot! (and so, 40% is even more).

That's, for every 5, 1, on average! That is shockingly high.

wow?
