"Patrick Walsh, 56, has been told he will not face any further police action after detectives found there were no suspicious circumstances." (MenMedia).

All charges were dropped (BBC).

Did you even read the article? I wrote that if we chase a burglar down the street and attack them, then it's not self-defence. Which is what happened here: "...he and his brother gave chase to the gang. ... Two of them got away, but a third, Waled Salem, was caught by the Hussain brothers, who proceeded to beat him with a pole and a cricket bat while he lay on the ground."

Again this didn't reach court (BBC).

Tony Martin. He shot them in the back as they fled, with an illegal firearm. Not self-defence.

Every case cited above confirms what I wrote. If a house-holder kills a burglar, the police will investigate, and if it turns out to be self-defence then it will not be considered a crime. Please before mentioning other cases, do some research to see what the outcome was. (Also, don't trust reports from gutter press like The Daily Mail. They distort details in order to provoke an emotive response from their readers.)
