Because of their more sophisticated roles in day-to-day police work, K-9 officers undergo training that is in many ways more intense and rigorous than the training received by human officers. Often, this training begins not long after they are separated from their mothers. A police dog is teamed with a human handler, and the dog and the officer will work as a team. To forge a bond between dog and handler, the police dog usually lives with his officer’s family. This not only encourages loyalty, but it helps to ensure the dog remains friendly and sociable.
The police are usually involved with criminals. It stands to reason that if you are dealing with crime as your job you’re going to encounter a lot of criminals, some of them deadly. As someone else pointed out here, the majority of police shootings ARE justified. There is a very small problem here and people are making a HUGE deal out of it while thousands are being killed in their own neighborhoods, and nobody cares about that. Please explain to me why a very few shootings is more important than a very large amount of shootings? This makes no sense at all. More to your point, the police do not control the color of the person that comes at them.
