A good thing.

Though the Tony Martin case is not a clear-cut one of defending oneself in one's own property, in fact far from it as Steely mentioned, there were loud reverberations of anger around the country in the fallout from the case. Anger that it was Tony Martin whom, it was widely perceived, the law pursued, rather than the two burglars.

Nobody wants to live in a situation whereby you fear prosecution for defending yourself in your own property.
