For decades local police, news media, and academics have claimed Victorians call in every little thing because they perceive phantom crimes that aren't actually happening, even as those same police and news media also admit that all sorts of stuff goes unreported because Victorians are jaded and take crime for granted. I'm tempted to file this as yet another contradiction in the narratives.
Anyone who knows the city knows the culture is certainly not about calling in every little thing. In 2003 we had store managers admitting to news media that they weren't bothering to call police even for blatant theft over a thousand dollars.
That 1960 news item about the high speed chase with bullets flying tells you everything. People who actually cared a bit were counterbalanced by people who didn't care at all. And even the people who cared seemed to be careful not to care too much. It was just an insane high speed chase with bullets flying that ended in a crash. No big deal.
