Yeah it is well known that all you have to do is claim that the police forged the evidence and then that evidence is immediately thrown out. If the police don't have hard cryptographic evidence than they are just out of luck.
It would be interesting to see what would happen if anyone ever tried the deniability defence in court:
"Ha Ha. You can't link those messages to my public key. They could of been forged."
"We can't for sure link your identity to your public key in the first place. Why should we care about any of this?"
