This horrendous case has got me wondering if Couzens had committed similar crimes before - it seems odd that he would go straight from flashing to rape and murder. Was this his first? Hopefully this is being looked into, but seeing as how it might reflect even more badly on the police if it was found that he was guilty of similar crimes, I do wonder.
On the other hand, maybe he was caught after his one and only such crime. It does strike me as somewhat stupid of him - especially as a serving cop - not to think he would be traced by CCTV etc. Didn't he use his own name and credit card for the hire car?
But maybe I shouldn't be speculating this way in public, as it keeps his name in the spotlight. I do agree with
existentialist and others when they suggest he should just simply be buried in the prison system and forgotten.
