Yes, I do have a basis for knowing that police are known to release information to the public in order to generate leads, even if the information is false.
The charge in the letter is that ILE released untrue info demonizing a suspect. You attempted to contend this was standard procedure in the U.S.
I have challenged that claim and you are apparently unable to support your original argument. Rephrasing it into a new argument does not support the challenged claim.
