From {qop} resembling the English word "cop", likely it means arrest that a policeman/etc does, not as in e.g. "A course of a new antibiotic arrested the progress of the infection.".

If you want to argue it that way, it would be a double pun for {qop} to mean "arrest" in the general sense but never in the special sense of what police do, and MO seems to relish multiple puns.
