It seems to me that what we need is a ‘protective’ legal shield for teachers as they have in yes I’ll call them ‘progressive’ States in the US. ( Of course my definition and President Obama’s view of progress probably don’t coincide by light years). Its time we set the agenda , not the liberal abolitionists who would willingly accept feral children on every street corner, as a price worth paying for maintaining the integrity of liberal orthodoxy in education and youth policy..
This type of law specified that a teacher can neither be sued , nor face criminal charges for incidents which take place under his/her duty to the employer, school or pupils, provided that he/she has made every attempt to comply with State law. This includes an absolute right of self-defence.The law does not indemnify abuse of ant form.
Of course , progressive states still retain the options of moderate corporal punishment, Saturday school, and other necessary sanctions. But as Plato asked us ….to whom do you take a young horse for training- the horse trainer, or the rabble in the market square?
