I had heard it was short for an English phrase "constable on patrol "

I agree with you but I have been called sexist for stating that there are biological and anatomic differences that give benefit to the other gender. When I have used an example like playing the top NBA team against the top WNBA team I have been rebuted with "the WMBA has not been around for as long. Really! The person could not SEE the difference? But in any case, stating that one gender is superior even for a specific task is offensive to some regardless of how true it is, and many will take a position against it just because of the subject. I have adopted a policy of just not addressing it (I know this post is in contrast) because it really doesn't make any difference to me and if the boxing match between the 2 top ranked heavy weight boxers (male & female) is not just obvious to someone I am not going to be able to explain it, nor do I wish to.

I understand but I hate it that you can't even say anything that is true. Men and women are not the same. If we were there would be no need for that division in sports.
