Another key point is that this is is exactly where you are going to find those kinds of predators.
I trained as a teacher in the late 1980s and so before a lot of the legislation or the culture that listens to the victims of this kind of crime, rather than the perps. In fact, the culture firmly favoured the perpetrators, I guess.
I dunno how common this was in education, or whether the thing we observed was a one off, or whether it happened everywhere. I was on a PGCE course with I forget but 80-100 others. Only a handful were male (primary teaching). One of the male students creeped us all (male or female) out. He seemed to have an unhealthy interest (we thought) in teaching girls' gymnastics. Really creepy looking bloke as well but he never actually did anything anyone could tangibly say was "bad". Many of us loathed PE and teaching it anyway and our course was so brief as to maybe only spend a few days, a week tops, concentrating on teaching PE including gym. So we didn't learn much most of us til we were on the job. But it was in the context of that I remember people saying "X is a bit into girls' gymnastics, isn't he?" and it was related to stuff he'd done in clubs etc out of college, IIRC.
At the final teaching practices only two students on the entire course were possibly going to fail - both male students, and he was one of them. But somehow they both scraped through and passed. But we heard that X, although he squeaked through and qualified, would have an "extra eye" on his during his probationary year (not sure how that worked but it was the case). Some of that because he had almost failed qualifying but some of that because of his unhealthy interest in girls' gymnastics.
These days he'd be failed, I have no doubt. They'd use his crapness in the classroom as an excuse to just not qualify him. I have been out of teaching for years and that probationary year got stricter after I left - but I also doubt they'd just "keep an extra eye" on a suspected paedo now. (Or how you'd administer that, given that the individual school decided whether you'd passed probation or not and all it consisted of was assigning you a "mentor" who was meant to watch you teach now and then).
This was in a very large city, around 1989. IIRC he went to teach in London. The other guy who almost failed - lovely bloke, but not one of nature's teachers lol - never taught anyway.
I do wonder if X got the PGCE purely to work in that environment, in gym clubs etc - but he'd have had to be a classroom teacher for a year first to get Qualified Teacher Status... I can't recall his name, now so can't go and see if he ever turned up in the newspapers.
