Henson case precedents

Well, the police have given up charging artist Bill Henson with anything. They never charged him in fact, never arrested him. Rather all they did was to barge into his exhibition and confiscate his work pending a charge, which is now not forthcoming, so the pictures will be returned.

No one is being charged because there is no case to be made. I.e. no law was broken in showing the pictures.

In this case, one wonders how it was possible for the police to move in to prevent the pictures being shown. The police furnish the answer that they had three complaints from the public. Moreover, they say that they would have acted on the basis of only one such complaint.

This is a truly extraordinary and completely unbelievable claim. If I phoned the police and complained that I, as I often am, am offended by some sexist piece of advertising, would the police move in to confiscate the offending hoarding? Or would they rather tell me to piss off? I presume rather heavily that the latter would be the case. Perhaps some kind of experimentation is called for. . .
