But perhaps that should come as no surprise as murder rates in the country have been tumbling for decades, while most of the killing is occurring in a tiny swath of the country. Furthermore, the 31 counties with the highest murder rates – just 1% of all US counties – contain about 20% of the nation’s population but account for 41% of all murders. Meanwhile, 90% of black murder victims are murdered by other blacks. Should police officers stop arresting blacks who are guilty of murder and other crimes so as not to appear racist? With any luck, the inhabitants of America’s toughest neighborhoods will continue to understand the importance of robust law enforcement in their lives, thereby enjoying a resurgence of safe community living and a further drop in the murder rate.
