What is always tricky about any attempt to use statistical prediction on something rare like criminality is that you have two things that are both true: the vast majority of crimes are committed by men, AND the vast majority of men are not criminals.
So what do you do with this information? If a crime is committed, you can guess with some accuracy it was likely committed by a man, but you can't arrest a random man and think he is likely the criminal.
Any attempts to preemptively limit male behavior is going to affect a lot more innocent men than guilty men.
Excellent point, I hope we can apply this to all demographic factors.
However, if we are limiting people based on potential for violent criminality, one category leaps out for effectively applying restrictions to, and that's men.
I'm totally against applying those limits based on potential violent criminality, however.
