Never a bad time to mention that besides killing almost 3 people per day american cops also shoot a huge number of dogs per year.

The Department of Justice estimates that American police officers shoot 10,000 pet dogs in the line of duty each year. It is impossible to ascertain a reliable number, however, because most law enforcement agencies do not maintain accurate records of animal killings. The tally may be substantially higher, and some suggest it could reach six figures.
...some animals have been deliberately shot and killed under questionable circumstances, including through doors or while tied, running away, or hiding. Studies show that some officers shoot pets unnecessarily, recklessly, or in retaliation, and that subsequent civilian complaints are investigated inadequately. Moreover, not every animal that police officers shoot is a large dog that may be more likely to pose a genuine risk to human safety—or even a dog at all. Police claiming a threat to human safety have shot puppies, Chihuahuas, Miniature Dachshunds, and domestic cats, among other pets. In some tragic cases, bullets missed their nonhuman targets and injured or even killed human bystanders instead.
