So this British Bill of Rights... the cost?

As you might expect, I have very deep misgivings about abandoning our foundational involvement in the European Convention on Human Rights (which we led the formation of, back in the 1950s). Nonetheless, our government has been elected to fulfil its promise to:

scrap the Human Rights Act and curtail the role of the European Court of Human Rights, so that foreign criminals can be more easily deported from Britain. (Conservative Manifesto 2015)

I am not going to go into the arguments for and against this proposal, there are people far more qualified than me to put those arguments forward (such as Liberty and Amnesty International)

But... remember when the Human Rights Act came in and every police officer and staff member went through training on it? As did people involved in mental health services, prison & probation services, social services etc etc etc....

So if a new 'British Bill of Rights' is established: how much is it going to cost to bring everyone up to speed on it? Are all public service officials going to be attending training in how to adjust their professional practice in the light of the new laws? And if people say, it won't be that different to the ECHR/HRA rights, then what's the bloomin' point in changing things in the first place?

Have these costs been factored in, Mr Gove?
