What actually was the charge recently which put that Headmistress in
prison for 5 months (or however long it was) for using an air rifle in
the street because they were threatening her?

She fired some shots from a CO2 gas-charged air pistol into the
pavement, and told the police that she had an air rifle too.

She was convicted of Affrey, and later "possessing a firearm with
intent to cause fear of violence"

She has been granted a conditional discharge and is no longer in
prison; however, her convictions stand, as IMO they should.
