Victorian Police

So I confirmed, when on foot the Victorian police like to patrol in threes... (and when doing nights in popular places they group in 4-6).  Foot patrols in Boston seem to be in pairs.  I have several theories.  By grouping in pairs Boston police can cover more area and perhaps be more of a deterrent in that respect.  Pairs are like what fighter pilots fly in.  On the other hand the 3 person unit seems to be the standard for infantry fire teams so I guess if trouble really starts brewing the Victorian police are better for mutual support and for bringing down lots of fire but then again gun violence is much rarer in Australia.  Hmmmmm
