The only ex government employee in trouble is the FBI agent who lied about taking shots. The shots themselves aren’t an issue. And neither is the justified shooting of Finicum.
They don’t have a case. They had a chance to get out of Finicum’s truck at the first stop, but they chose to stay.
One plus one confuses you, doesn’t it ?
The FBI agent isn’t an ex-employee, he’s still on the payroll but doing different duties ahead of his trial.
