They here not horrible, and they crimes are not exaggerated - they simply exist. They here not ignored nor are ok, and that is what you want to do. The police don't need to commit crimes to catch the criminal, but in your logic, is ok if do.
No, what I'm saying that just as it isn't criminal for the police to kill a shooter to save a hostage. Likewise, it isn't criminal to indiscriminately bomb legitimate industrial and military targets. In both cases things could be done differently; the police could try to incapacitate the shooter without killing him and risk him shooting numerous hostages, just as the Allies could carry out precision bombing and risk thousands of airmen futilely dying and the Nazi war industry continuing to produce weapons to be used to kill millions.
