I’m not sure how I feel about this one. I think the cop might be getting screwed. He was arrested for possessing a gun but one of the guns they caught him with, I believe, they gave him when they hired him to be a cop:

Smith was an officer in south suburban Harvey when he was arrested for mail fraud in 1997. He was fired after he was convicted the next year. He served four months in prison and received two months of probation, records show.

Despite his conviction, the police department in south suburban Markham hired Smith as a police officer in January 2006, prosecutors said. Smith was on the Markham force until October 2010 when he was fired because he did not have a state Firearm Owner’s Identification card, which Illinois residents must have to possess a gun. State law bars felons from receiving a FOID card.

After his firing in Markham, Smith landed a K-9 officer job in Robbins. Smith was arrested Thursday. Investigators found a loaded handgun in a duty belt in the back seat of Smith’s car and discovered another loaded handgun during a search of his home, prosecutors said.
