CHICAGO (AP) — An appeals court in Chicago has reaffirmed that your Facebook posting can potentially be used against you in court.

The Chicago Daily Law Bulletin reported Monday that the 7th U.S. Circuit Court of Appeals rejected convicted gunrunner David Lewisbey argument that Facebook photos of himself surrounded by guns shouldn’t have been admissible. It upheld his convictions for buying guns at Indiana gun shows, then reselling them in Illinois.

Lewisbey first drew the scrutiny of agents after bragging about running guns on Facebook. The three-judge panel found there was no reason to doubt the photos were, in fact, posted by Lewisbey, including because some of the same photos were on his cellphone.

Lewisbey argued he was a gun collector. But Friday’s ruling said there was “prodigious evidence” to convict him.
