Honestly I've always hated this. An early example of the awful trend where there has to be a "lore reason" for every little detail.
Star Trek aliens are mostly humanoids because its a human TV show telling stories that have to be relatable to humans and also has a limited budget. There is no need for a lore explanation.
At least in this case it's a one off that's never really referenced again.
Yeah I know its straight out of the Fascist playbook, but this is way to conveniently timed and flawlessly executed. Its going to take some pretty compelling evidence for me to be convinced that this wasn't a false flag. I definitely wont trust that its whomever the regime eventually pins it on.
Charlie was a disposable pawn of right wing moneyed interests, and he will continue to serve those interests in death.
