As some of you know, a member of my family suffered what was used to call an indecent assault at her workplace some years ago. I told her she should go to the police, others said it would be useless … in the end, others were right. Her word against his, “misunderstanding” etc. But that is certainly still what I think should happen, even though it can be easier said than done.and even though the short term outcome might be nothing. Get it on record.

Reporting sexual assault to the police is particularly harrowing. You need to go through what happened in detail, which can be as traumatic as the assault itself.
