But the "rate of such incidents" is amazingly low. For every Forest Gate or Jean-Charles Menezes, there are hundreds if not thousands of police raids and operations involving the same intelligence systems and firearms officers that go off without a hitch. No shots fired, person guilty of exactly what they were supposed to be guilty of, legal system chugs away. But that doesn't saturate the media. Yes, the one or two situations have occurred and that is regrettable, and it gets investigated. But to demand absolute perfection and infallability of a force that comes down to humans doing their best to protect others is unreasonable. Nothing is perfect, we can only make sure it's as good as it can be.
