If you want to get a sense of the devastation that an accusation of child abuse can bring to a family, watch the DVD of the documentary Capturing the Friedmans.
This apparently respectable, middle-class family was torn apart in the 1980s when the father, Arnold Friedman, was found to be importing child pornography magazines from The Netherlands.
Police then charged both him and his son Jesse with the abuse of children attending computer classes in their home.
The movie, released in 2003 and directed by Andrew Jarecki, leaves you, at the end, with a sense of confusion and with nowhere to go.
One the one hand, Arnold Friedman, who committed suicide in prison, was a paedophile. On the other hand, the police investigation was flawed in ways that would be unlikely to be tolerated today.
Jesse Friedman, who served 13 years in prison, continues to try to prove his innocence.
A remarkable documentary, all the more remarkable for its refusal to neatly tie up the answers for us.
