I read that there was possibly both drinking and target practice being done on the set prior to this tragic accident. At least Alec is fully cooperating with the authorities and is keeping in touch with the family of the lady that was fatally shot.
I, honestly, think this was a tragic accident that should have been prevented happening by the people in charge of the prop guns & the real guns onset doing their business to make totally sure that something like this wouldn't happen - and my hope and prayer is that real & prop guns on movie sets from now on are very thoroughly checked.
