The holiday thing is a distraction (and I agree term time holidays aren't cool - although I don't think that should mean they are crimes).
The real point is that today the judge criminalised every single unauthorised absence. This now gives a headteacher complete discretion over whether or not you get a criminal record if you keep your child off school or your childminder drops them off late. Many heads are great but some are morons. They now hold a lot of power.
There have already been many cases of a parent informing the school that the child is too ill to attend and the headteacher disagreeing and arranging for the parent to be fined. Now the parent will also get a criminal record.
Illnesses like scarlet fever, measles etc are massively increasing because parents are scared of letting their children be off sick.
Agree with everything DoloresTheRunawayTrain said, and feeling very depressed how many people have missed the point of what happened today.
