Sometimes children make vindictive allegorations that are later proved to be false.
For example allegiations of sexual abuse where it is quite easy to prove it did not happen. It is done out of pure and utter spite, but the stress of being suspended while the allegorations are investiaged can make an innocent teacher suicidal.
I think that if a teacher is exhonerated of a such an allegoration that the child should be permamentally excluded. With teenage children I think there should be criminal charges if it can be proved beyond legal doult that they lied.
The sad thing is that with children making false allegorations out of spite is that reports of real abuse do not get listened to.
Prehaps there needs to be extensive CCTV cameras in schools to protect children from the possiblity of being abused or teachers having false allegiations made against them.
