This surveillance video shows the events leading up to the fatal shooting of Shane Tasi in Mountain View on June 9 by Anchorage Police officer Boaz Gionson.

On Wednesday, it was announced that an investigation by the Alaska Attorney General's office cleared Gionson of wrongdoing in the 9:30 p.m. shooting on the 700 block of North Bunn Street.

Witnesses said Tasi aggressively approached Gionson and refused instructions to drop a stick he was carrying. The officer fired three times, according to witnesses at the time, killing Tasi.
