A complete “he said” “she said”.
She has plenty of reasons to lie.
Why believe her over him?
Because, we are told: Women never lie!
There could be evidence, but none was mentioned. It is pretty close to “He said, She said”, in which case 50:50.
Because she reported immediately and didn’t wait 30 years?
I was foreman of jury trial. The first vote was 6to6 guilty not guilty. I asked the proponent of each side why they felt as they did. Guy said he was innocent because his girl friend said he did not do it; WOMEN DONT LIE!
