They shot him from across the street, with poor visibility, from a semi concealed position for pulling up his pants. There are no non-lethal tools that would have worked at the distance they were at and the man would have had to have been a fantastic shot to pose a risk to the officers based on the distance.

In the video the officer who fires is to the left of the speaker. Caution you will see someone getting shot to death.
