I think it's still a large leap to presume that sexual predators are more likely to commit sex crimes if they can cross dress to get into a women's restroom. The guys who got caught doing those things (once again approximately 3, in the course of 5 years or so) would have certainly decided to act out their perversions in one way or another.
Keep in mind 82% of rapists are friends, family, and acquaintances, so children are literally safer in strange restrooms than they are at family reunions. That's why this seems like such a bizarre disconnect. There are tons of ways to mitigate child endangerment, and almost none of them have been actively taken out. You could definitely put a much larger dent into child sexual abuse by banning homeschooling. But that might actually inconvenience the people railing against trans people, so that's a non starter.
