I recall that part of my 41 years in the police I spent teaching and training detectives, and as the detectives would come in—these are people that have come in, they have reasonable knowledge of the law, they've spent time on the streets as uniformed police officers, didn't really need the in-depth knowledge of, perhaps, the Crimes Act or some of the serious legislation that they'd subsequently need as detectives. Well, the first thing you'd do when you start testing—they would open up the Crimes Act and start looking at the variety of offences in there. The first thing they would sit and do is they'd go through the assault provisions and the various definitions of them, and they'd sit there and say, "Well, what's the difference between that and that?" Essentially, you're talking about injuring, wounding with intent—a large number of offences. Just about all those offences had been put in there to satisfy, generally, a political requirement at the time, because they didn't make anything safer.
