Was it all just a terribly unfortunate accident, or an attempt to smokebomb out?
Not kidding, but a simple length of appropriate wire can be twisted and fashioned into a functional component to “enhance” the fire control characteristics of a common AR. Now, for most shooters, expending high cyclic ammo is simply not advantageous, in most settings.
However, in a down and out fight against sedition and treason… it might be necessary, in some circumstances, for some in a coordinated maneuver to send lots of rounds willynilly into the face of advancing criminals. Me thinks it very possible, that such criminals posing asif legitimate GOV/ATF/WTFs… are aware of this kind of thing, are understandably trying their best to convolute ‘The Law’ to protect their criminal operations.
