These three lads are Murray’s personal “guard dogs” – loyal, strong and not too bright. As Murray was recruiting his security staff, moral integrity and impeccable job history were not among the characteristics he was interested in. Most of all, he wanted people who can handle themselves in a fight, know how to use a gun and are not particularly afraid of the coppers.
The three lads will hurt or kill anyone if Murray tells them to do so. They are mean and violent, but once they meet Olive, they will wish they had chosen a different line of work.
