While this is most specific to the United States, I’d suggest it’s something the average motorcyclist needs to consider when talking to employees of the Queensland Police Service as well:
Are there mundane situations in which you might rationally decide to talk to the cops — say, if a neighbor’s house is burglarized, and they come to ask if you saw anything? Sure. But you should view each interaction with the cops with an extreme caution bordering on paranoia, as you would handle a dangerous wild animal.
Should it be this way? No.
