It makes me sad to see that is the current culture of US police force. It would interesting to know why and how the European and American cultures have grown apart so considerably on this matter. I think in 19th and 20th century we were both pretty blood-thirsty although I'm not sure were the American police force then already considerably more accustomed to use lethal force. Now it seems that it's such an integral part of the American police officer's identity that the stereotype already feeds itself by people expecting them to behave that way and them in turn behaving as they expect them. Of course in the US the people have more guns so police for sure has more reason to fear for getting shot but the use of lethal force still seems excessive.
