Most leo agencies dont want to be recorded ...not just fbi
IRS often wont talk to you either if you insist on recording them
I know there are plenty of good cops but the system in general is generally f*cked and geared at success via intimidation ...if for one year every single person charged with a crime demanded and went to trial the syatem would completely collapse...which leads me to the conclusion we have far too many laws.
There are many police interrogations that are video taped.
That the feds don’t is all about corruption
