The Truth about 302s is that they need to be banned as made up BS hearsay.
The whole FIB process is corrupt.
Keeping that nonsense going in an era of ubiquitous recording devices is so crooked its unbelievable.
Everything I have heard about the process tells me that anyone asked to answer questions should decline to do so, unless legal Counsel and a Court reporter are present.
How right you are.
In today's world, where every 4th grade student has a recording device, both audio as well as visual, that fbi agents doing interviews that can result in someone's freedom on the line, that they are still making up written reports of their recollection and their impressions of the guilt or innocence of the person being interviewed.
Remember, the fbi can lie to the person, but if that same person 'lies' to the fbi, they go to jail.
