The FBI opened investigations into individuals because they received information from the public that these individuals might be making threats to others and inclined to cause harm. Seems normal. I would expect that such things happen every day. After-all, it's called the Federal Bureau of
Investigations for a reason, right?
Are you making the case that the FBI should not investigated tips from the public? Or are you making a case that the FBI make exceptions in the interviews/investigations for parents, Republican law makers and anti-mask/anti-vax individuals? Do you think that the FBI should be free to act on information it receives and then make its own determinations? Even if the initial tip is politically motivated?
Oh, and that woman that said "We're coming for you,". Here's the full quote:
“We’re coming for you. Take it as a threat. Call the FBI. I don’t care. You’re all either going to be recalled or you’re all — we’re all coming for you. That’s what’s happening.”
That's about as close to a death threat as you can get without saying it directly. If I was a member of a school board and someone with access to firearms said that to me, I'd feel fine calling in the police to ask a few questions of her.
In another case, the adult child of a member of a different school board had this sent to their home (prompting the FBI to open an investigation):
“It is too bad that your mother is an ugly communist [word meaning female prostitute]. If she doesn’t quit or resign before the end of the year, we will kill her, but first, we will kill you!”
Another
22 individual death-threats were sent to members of that particular school board.
In yet another case, a school board member received threatening letters for more than a year. One evening, they came home to find their dogs had been poisoned. Guess what - the FBI opened an investigation into that as well.
