I had a friend get a lot of guns stolen in the 1980's while he was at church; someone knew his routine. Several years later he saw his Sako varmint rifle on a Gunshow table. He played it smart and didn't say anything; just went to the promoter and the Deputy at the door with a copy of the police report that he always carried with him. Deputy went to the table, checked the rifle against the report and handed him his rifle.
