Hi.

You seem to have answered your own question.   I'm not sure what further discussion you were hoping for.
You have a similar civic duty to report this as you would to report other crimes.

Best Wishes.

It always struck me as odd that being in possession of an image of some crimes is a crime, but not of others. Every christian church has at least one graphic depiction of a hate crime, and some people like to wear a representation of an instrument of torture in public, presumably to signify their approval. Some even symbolically practice cannibalism on Sundays. But nobody is ever prosecuted for it. Is antisemitism really that deeply ingrained into western culture that such abominations are excusable?

Apropos child porn, I find naked cherubs repulsive but there are plenty on the walls of public art galleries. Is the medium really the message?

A year or so ago I watched a TV documentary about life on a warship. At one point the Marines were tooling up to board an enemy gunboat and beat the crap out of the baddies. They set off, armed to the teeth in a helicopter and a couple of boats, then cut to the adverts. As the program resumed, the announcer warned that the following full color record of real life bloodbath and mayhem  "contains offensive language". 

Who draws the lines, and where?

In what way a hate crime? The rulers hated him?

Torturing someone to death because of their religious utterances cannot be considered a crime of greed or lust. What else motivates anyone?

[paul cotter]

War is an undoubted obscenity but there is nothing realistic an individual can do about it. Abusing a child is a despicable crime and disrupting the supply of such material is a positive act. I am not naïve enough to believe it will ever be stamped out completely. Apart from the harm to the child in such material there is a danger that the viewer may become an abuser him(her)self. Sexual fantasies are very powerful.

Power and money? I have heard that on the odd occasion that these can be factors.

This is a sound argument. It is the reason that people pay lots of money to advertise their products in the hope of altering other folks' behavior, and it works. So why wouldn't the depiction of violence  induce the viewer to become violent?

[Bored chemist]

Imagine yourself trying to explain to the child why you did not report it.

[alancalverd]

Or indeed to the victim of any other crime depicted on public television or religious painting.

One difference may be informed consent.
But I agree, it's slightly sick that people wear crosses.

[alancalverd]

Not much informed consent in war these days, but plenty of documentary footage and even depiction of extreme nonconsensual violence as entertainment, Mr Bond.

[paul cotter]

The depiction of violence most likely does propagate such behaviour. Welcome to a world of many, many problems.
