So from what Ive been reading, people think the cop may have thought the gun was his taser. Cause he drew, and shot 3 seconds later.

And the frame of a taser and a Glock are very similar, and with all that adrenaline pumping, it would be hard to tell teh difference that quick by touch alone. Thats why most officers keep their gun on their strong side and the tazer on the weak side and cross draw.

But he is probably going to get something like manslaughter.
