Ah yes, we studied this in English back in high school. An interesting, yet unbelievable story. Hanged for shouting 4 simple words; "Let him have it".

Ah, just found that it was Derek Bentley that was hanged. Christopher Craig was the one who fired the gun.

There have been many injustices during Britain's long history & I wouldn't go so far to say that this is the worst, even in the last Century. It was significant as it involved the murder of an unarmed policeman. As Tweek points out, Christopher Craig who had the gun & shot the policeman was 16 & therefore below the minimum age for execution. His accomplice Derek Bentley was 19 & made an example of. He was presented in court as a callous monster who egged his younger friend on when the opposite was probably true. Craig actually served 10 years before being released.
