Luftwaffe pilots shot while parachuted

[Broncazonk]

Important note: I am not trying to minimize the historical record (nor contest it) with this post.

I have read, (I do not know the source) that many USAAF fighter pilots attempted to capture images of the parachute (of Luftwaffe pilots) with their gun cameras to confirm the kill. During this process, the .50-cal. MGs were sometimes fired resulting in the death of the man in the parachute. There was a way to disconnect the gun camera from the MG trigger--it was possible to turn the gun camera on without firing the MGs--but this did not always happen.

Is the above scenario a plausible explanation for at least some of these deaths?
