I am surprized that you ask that question of me. You yourself know in life things happen of which we do not have answers for. But they happen! Especially in wars or conflicts.

Operation Carthage, on 21 March 1945, was a British air raid on Copenhagen, Denmark during the Second World War which caused significant collateral damage. The target of the raid was the Shellhus, used as Gestapo headquarters in the city centre. It was used for the storage of dossiers and the torture of Danish citizens during interrogations. The Danish Resistance had long asked the British to conduct a raid against the site. The building was destroyed, 18 prisoners were freed and Nazi anti-resistance activities were disrupted. Part of the raid was mistakenly directed against a nearby school; the raid caused 125 civilian deaths (including 86 schoolchildren and 18 adults at the school).

Can we justify that bombing? The RAF ?....causing 125 civilian deaths??
