A new offence has been created in England and Wales, so what effect will it have on the courts, prisons and policing?

In Scotland, its been illegal since 2010, but 95% of reported offenders do not receive a conviction, so it will likely go one of two ways.

a)  Hardly anyone bothers to report it, because they don't think the police will take it seriously, meaning very few will be convicted.
or
b) There will be lots of prosecutions, the courts will be overwhelmed and the judges will be told to stop sending people to prison for it, because the prisons can't cope.

Personally, I'm betting that it will be option (a).
