Every news organization is biased. Unless you hear it from the horse’s mouth, it’s probably speculation. I don’t think it’s unreasonable to ask a person if they have any proof of this. Most people have no actual way to defend their opinions besides linking to another opinion—this includes me and you.
It’s also pretty unlikely that any real information would be released because of “national security.” Neither party wants people to side with him, because that might encourage copycats.
My guess is that he has no firm political party preference. I’m a registered democrat, but I’m hardly a fan of them. He was wearing a D/R shirt when he got shot. And as I’m sure you know, they are focused on giving power to the people, as opposed to a central government. Assassinating the leader of the central government is pretty on-brand. However, I’m sure the political ideologies of that group have probably shifted since 1820 😅
A good way to tell if a company has ever been shitty to their employees is if they have a union. Unionizing is no easy task, and for things to get that bad it usually requires a shitty corporation.
Pay your people well. Treat them like your kids. (In the Norman Rockwell, everything is perfect, sort of way 😅)
