About guns.......

[barbara]

Recently, Alec Baldwin accidently shot someone on the movie set and it killed her. I'm sure you have all heard.

Now he has had an interview where he states he never pulled the trigger on the gun.

As you know, my knowledge about guns is not great, but, even as uninformed as I am I can't believe a gun can shoot without pulling the trigger.

What am I missing here? Is there something about guns shooting without pulling the trigger that I don't understand or is Alec Baldwin just saying anything to avoid responsibility?
