the film maker has already undermined his own credibility by using a solo sting song as the basis for the word-play of the title "set them 3". (eg "if you love someonem set them free")
yo! some advice - if this is a doco about the police, at least use a police-ish title, rather than a sting solo-referencing title.... is this a sting doco or a police doco?
your title should reflect the content of the film.
just my 2 cents on the soap box....
