David Chipman, Biden’s nominee to be Director of BAFTE, is not only anti-gun but a delusional liar.
He participated in a Reddit AMA or Ask Me Anything. During that AMA, he asserted that the Branch Davidians shot down two Texas ANG helicopters in Waco with two .50 caliber Barrett rifles.

According to a list of firearms recovered from the compound after the fire that destroyed it, there were zero .50 caliber firearms regardless of maker. This list came from the US Department of the Treasury based upon a dual FBI and Texas Depart of Public Safety search of the Branch Davidian compound.
As the case agent assigned to the trial of the surviving Branch Davidians, Chipman must have known this. If he didn’t, he was derelict in his job performance. Thus, we can either assume Chipman is an incompetent or a liar. You make the call.
