I did ten heard as a copper plus 3 as a civvie.
Not once did I hear anything like that. I never saw a rape victim shamed, ignored or mocked. Never saw evidence laughed at, and sure as hell wouldn't have allowed it on my watch.
I was a detective, so dealt with LOT of rapes, sexual assaults etc including both victims and perpetrators.
Yes there is a massive machismo culture. Yes it's a huge problem. No, these comments are not normal.
