Presumably not the UK?

https://en.wikipedia.org/wiki/Tony_Martin_(farmer)

"Anthony Edward Martin was an English farmer who shot two burglars in his home [...] was convicted of murder, which was later reduced to manslaughter on grounds of diminished responsibility"

"Details" matter:

> The prosecution accused him of lying in wait for the burglars and opening fire without warning from close range, in retribution for previous break-ins at his home.[13]

No warning shot.

He also llegally bought a semi-automatic pump shotgun, possibly with the explicit plan to kill the intruders (as he got robbed in the past).

He also shot at them while they were fleeing.

So, yeah, in this particular case the judge decided that what he did was not covered by the law.

Where exactly is the imminent threat of deadly force in that example?
