New questions surround use as tasers are found to be 'ineffective' more than 30% of the time

New questions are surrounding the use of police taser guns after the devices failed to subdue a toll evader with a knife in Brooklyn on September 15.

Police body camera video shows the actions two officers took when Derrell Mickles didn't follow their commands after toll evading twice and displayed a knife. Less than a minute after the officers caught up with Mickles on the Brooklyn subway platform, they deployed their tasers but the devices didn't work to stop him.

The video appears to show the suspect pulling the metal probes from his clothing and leaving the subway car.

After the tasers were ineffective, both officers then opened fire, striking Mickles, two innocent bystanders, and one officer was also hit by the other officer's gun fire.
