A smart person does not deliberately tear gas journalists. A smart person does not point a rifle an an innocent person and tell them that they are going to kill him. A smart person does not severely beat a person with down syndrome because he sees a bulge in his pants, which is actually a colostomy bag. A smart person does not continuously shoot at an unarmed man who posed zero threat and whose arms are in the air.
If more people knew this information you could rest assured that they would try and reform their police departments. No one wants their police officers to be unintelligent, right?
