I am not comparing the damage - there would be no damage, because I would not take a dog even vaguely likely to cause damage, to hang out near a school.
As I said if the dog is ready for that level of exposure...
A dog likely to cause damage to a child is not ready for that level of exposure.
See?
Or are you suggesting that any dog bigger than a chihuahua should NOT be trained to ignore children, be engaged with the owner and able to listen around children, be safe and reliable, around children.
Because that is a bit bloody silly really. It is almost as if you're looking for something to get hysterical about.
And again, the duration of a training session is so short that by the time you've got through to the police, I've buggered off again. And if they show up and speak to me, I'll point out I am dog training in public, a safe distance away from a school, which is not dodgy or illegal, and is in fact me being a responsible owner/trainer, trying to ensure my dog is safe in public.
I wouldn't suggest someone went out of their way to seek out a school, but if as the OP does, you live where a school is on your route, I really can't see the problem. If you want your children completely 100% isolated from ever clapping eyes on a dog - um, live in a bubble? on a dog free deserted island?
