It's also important to remember that police go into what they understand to be life or death situations. When we look back on these incidents they seem horrible, but if you give someone a gun and give them a reason to believe their life is in danger you're probably going to get deadly consequences. It's obvious to us that the cops life wasn't in danger in the instances you mentioned, but people are fallible and they may have brought past trauma or prejudice to the incident. It's probably extremely rare that a cop actually wants to murder someone and is looking for the right opportunity. That said, if cops had better non-lethal alternatives to guns, we could save lives. Something that is more effective than tasers and works immediately at a distance. The cops objective in a potentially deadly situation should be to immediately incapacitate rather than kill.
