This is an Inspector Clouseau short from Depatie-Freleng. There will be spoilers ahead:The Inspector is chasing a jewel thief around the world. When they reach London, the fun really begins. The Inspector makes the acquaintance of a detective from Scotland Yard, who scolds The Inspector for firing a gun, driving home the point by bashing him on the head. That the jewel thief is also firing a gun seems to escape the notice of the detective, who is of little to no help to The Inspector.That's basically the running gag-Clouseau repeatedly finds himself in a gun fight against the thief, only to have the detective assault him for having a gun while ignoring the thief.Eventually, The Inspector catches the thief on his own and then comes the ending gag, which is the best one in the short.This short is on one of two DVDs which compile the 34 Inspector shorts. The DVDs are well worth having.
