> Contrary to the facts; untrue.
Your claim: "the first [police were] the Bow Street Runners".
Not your claim: "the first police force in an English speaking country was the Bow Street Runners"
The fact: The Bow Street Runners, created in 1749, were not the first police force as there were at least one other police force before them created in 1667 by King Louis XIV in France [1][2].
Your claim is contrary to the facts. i.e. it is counter factual. Not sure what about that is unclear to you.

Also I would ask for a citation for your claim that the derogatory term for cops started before or with the Bow Street Runners but if we were to, colloquially speaking, face the facts, then it is not likely that you would be able to produce such a citation... you could always prove me wrong though.
