From the report:
Officers expect and demand compliance even when they lack legal authority. They are inclined to interpret the exercise of free-speech rights as unlawful disobedience, innocent movements as physical threats, indications of mental or physical illness as belligerence. Police supervisors and leadership do too little to ensure that officers act in accordance with law and policy, and rarely respond meaningfully to civilian complaints of officer misconduct. The result is a pattern of stops without reasonable suspicion and arrests without probable cause in violation of the Fourth Amendment; infringement on free expression, as well as retaliation for protected expression, in violation of the First Amendment; and excessive force in violation of the Fourth Amendment.
In January 2013, a patrol sergeant stopped an African-American man after he saw the man talk to an individual in a truck and then walk away. The sergeant detained the man, although he did not articulate any reasonable suspicion that criminal activity was afoot. When the man declined to answer questions or submit to a frisk—which the sergeant sought to execute despite articulating no reason to believe the man was armed—the sergeant grabbed the man by the belt, drew his ECW [i.e. taser, AT], and ordered the man to comply. The man crossed his arms and objected that he had not done anything wrong. Video captured by the ECW’s built-in camera shows that the man made no aggressive movement toward the officer. The sergeant fired the ECW, applying a five-second cycle of electricity and causing the man to fall to the ground. The sergeant almost immediately applied the ECW again, which he later justified in his report by claiming that the man tried to stand up. The video makes clear, however, that the man never tried to stand—he only writhed in pain on the ground. The video also shows that the sergeant applied the ECW nearly continuously for 20 seconds, longer than represented in his report. The man was charged with Failure to Comply and Resisting Arrest, but no independent criminal violation.
