It seems that things got out of hand down under, when a police officer attempted to justify his out of line actions as a "PR exercise." According to Australia's ABC News:

A Northern Territory police officer has had disciplinary charges laid against him for firing his gun next to a car full of women and children, and then describing it as a PR exercise.

The incident was reported to the Northern Territory ombudsman, who says the officer pulled over the car, asked the people inside whether the gun he was holding was loaded, pulled the trigger and then asked the children what they thought of it.

PR is used to having its name dragged around in the mud, but this is a bit much. Intentionally firing a gun in the presence of children? This is not an exercise we'd ever recommend.
