Yeah, the father wouldn't make any comments on his son, his mental state or motive but had a well rehearsed diatribe on gun control. It's time to get fitted for my tin-foil hat, because this stuff has to be orchestrated to some degree. And if not orchestrated, someone "got to" the father beforehand with a script.
Yep, "Sir, we will pay you $XXX,XXX to push our agenda forward. If you don't comply, you won't see daylight again." Or something to that degree. (where the hell is my tinfoil hat?)
