Why did she sign it?
well, many 15 year olds do disobey orders. I'm afraid a 15 year old is an autonomous young adult.
There's no reason they cannot do this. Such a statement would have no bearing upon any criminal investigation. Probably the fact of an admission could be given in evidence but it wouldn't get over the legal hurdle of a confession. It would just be a piece of evidence like any other.
But there is no reason the school cannot conduct their own investigation and, in fairness, of this is an allegation of drug dealing then they must investigate. Can I clarify anything for you? Jo
Well, that would not be admissible if this were a police interview but it is not.
The trouble is that schools do exercise a quasi judicial approach. They deal with discipline. They are not covered by PACE and never have been.
That, of course, is not to say that they are not wrong. Teachers are nothing special. Generally speaking they are not a particularly high calibre of graduate and do tend to have delusions of grandeur essentially because they are dealing with children and they can always accuse them of insubordination if they cannot win the argument on a proper basis.
the police won't be interested unless they can find a substance they can analyse. Otherwise they can't prove it is a prohibited substance.
Please don't worry. They are much too busy investigating claims that a person tried to kiss another one hundred years ago to do any proper crime.
That is probably right.
Anyway, academic qualifications these days don't mean that a person is particularly well educated and they certainly don't mean they are sensible.
