Rubber bullets introduced by the RUC in NI were designed to be ricocheted off the ground to strike legs and knees. They weren't accurate enough for much else.

Later replaced with plastic baton rounds which were fearsomely accurate and were used in direct-fire. Forbidden to aim at head but instead aimed at stomach and let bullet-drop do its thing. Given the majority gender of the 'opposition' you can guess the results.

There was a minimum range ( 25 metres or so ) which could only be violated to save life. Absolutely not permitted indoors.
