Zip ties
About 10 or so years ago, I remember there were some news stories about how police were starting to use zip ties as a replacements for handcuffs. Today CoziTV was playing the season 7 episode 'Suicide' and there was a scene where Malloy and Reed (and an old lady) took down a group of 5 guys who were stripping a parked car. After each of their regular pairs of handcuffs are used, Malloy gets to the third guy and pulls out a zip tie. This is 1975, around 30 years before the media was acting like it was a new idea.
