Nevertheless, according to the Bureau of Justice Statistics, 400 to 500 innocent people are killed by police officers every year. That does not include the number of unarmed individuals shot and injured by police simply because they felt threatened or feared for their safety. This is the danger of having a standing army (which is what police forces, increasingly made up of individuals with military backgrounds and/or training, have evolved into) that has been trained to view the citizenry as little more than potential suspects, combatants and insurgents.
