The third account — the psychology of willful blindness — is perhaps the most uncomfortable to consider because it allows the family to be neither entirely victimized nor entirely complicit.

It suggests that human beings, under the right conditions of grief and desperation, can choose not to know things they suspect.

The documentary The Imposter, which is careful and unsensational in its approach to these questions, does not resolve them.

It presents the different perspectives and allows the audience to sit with the complexity rather than resolving it into a simple narrative.

That complexity is part of the truth of this case.
