Are you serious ? Do you think it's ever going to come to light what tactics the police might use in cajoling certain members of the public to " play ball ?"
So officially it's never happened before.
No members of the public have ever accused the police of asking them to pretend they found something.
No released criminals or aquited people have ever accused the police of asking the public to pretend they found something.

Things are not looking good for supporters -
It was impossible for the relatives to fabricate the silencer alone. See thread post.
The police didn't need the relatives to pretend they found the silencer. It would just make their frame 10x riskier.
There are no other examples of the police asking the public to pretend they found something for them.
Not sure what else is needed.
