THAT'S EXACTLY HOW SINGLE ACTION WORKS

You can't fire a single action handgun until & unless you cock the hammer... which he did...

-- "Baldwin discussed how the firearm discharged. He said that he was instructed to cock the gun and that he pulled the hammer back, and then when he let go of the hammer, the gun went off." --

ALEC BALDWIN - SNIVELLING COWARD:

-- "Just when you think Alec Baldwin can’t go any lower, he blames Halyna Hutchins, the woman he shot to death, for getting shot to death." --
