If a crime is committed against society, society has the right to demand justice. Police blunders should not preclude that. Obviously that is a broad stroke.
Or, do we need to defend the rights of those who were engaged in acts that denied other people their rights?
Have fun with that one....
Crimes are NOT committed against “society.” Crimes are committed against INDIVIDUALS. Just as there can be no such thing as group “rights,” there is no such thing as “group victims.” Only individuals.
