Spanish query

[petrusplancius]

I would be most grateful if anyone could help me out with a Spanish idiom, an expression appearing in a discussion of torture from the late 18th Century. The author says that he regards torture as being a 'proof not of the truth' but.. '(permítaseme esta expresión) una prueba de bomba judicial'. What is he meaning to say?

means torture destroys the judicial process as if by a bomb

bomba по-испански - это ещё помпа, насос, даже сначала - помпа и насос, а потом бомба :)
так же это ещё часть оч. многих идиом…

так что тут игра слов

Спасибо.

So maybe I have been looking for a subtlety here that doesn't exist, just a straightforward metaphor!
