I have seen too much conspiracy. And, i have seen too much real crime.
This falls so squarely in the conspiracy camp.
People get shot all the time. And the police don't say nothin, even to the family about the investigation.
What i expect, looking back from the future, we (the populous) will find Luigi in some foreign country living out a quiet life. This is after he was to be sentenced to 2x life without parole.
While, some sleuth finds the real guy who did the pistol work, and their life is so Kazinski-like, that we have to wonder if anything is real.
And all of this will happen while VAXXXed people (or family) go insane.
