@Lustig Andrei,
The only time I get to see a cop on foot, directing traffic, is when the traffic lights are down.. That happens though at least once a year, somewhere where I am travelling...
In the City of Adelaide, there will always be police walking down Rundle Mall, the main city strip.. Apart from that, only cars. Actually, notibable these days and not being offensive, is alot of the older cops aren't that fit, if you know what I mean... Maybe it's because they sit down too much
All police here have a revolver on their belt, unless they are off course in training.. What freaks me, is arriving at International Airports especially Asia, where it's not a 9mm rather, a rifle..
