Imagine people on FB passing on a picture to all their friends. “This guy is a child rapist. Do you recognize him?”
It would be like swatting. Good way to destroy someone.
I would agree with that, unless the person’s photo had been taken from something showing him doing something very bad.
Perhaps the best way would be to explain that this person was wanted for questioning by police officials, and needed to be found right away.
You wouldn’t have to be specific.
BTW: Anyone shown to be swatting someone in this manner, should face a severe penalty on the order of a decade or two behind bars.
