We can only assume that rabidly anti-gun mayor Rahm Emanuel and rabidly anti-gun (and inept) police superintendent Gary McCarthy are fuming that, even in Chicago, concealed carry thwarts crime and saves lives.

A robbery was thwarted at a Southwest Side corner store Saturday night when a patron with a concealed carry license shot and killed an armed robber, authorities said.

The dead man has been identified as Reginald Gildersleeve, 55, of the 5000 block of South California Avenue, according to the Cook County medical examiner’s office. Gildersleeve was pronounced dead on the scene at 7:10 p.m., according to the medical examiner’s office. An autopsy is slated for Sunday.

Citing preliminary information, police said a man walked into a store around 7 p.m. in the 2700 block of West 51st Street in the Gage Park neighborhood on the Southwest Side, announced a robbery to an employee working behind the counter and displayed a handgun.

Another employee came from the back of the store and the gunman pointed his weapon at her, police said. He then made her go to the back of the store, which also serves as a currency exchange.

After that, a customer who was also inside the business pulled out a gun and opened fire at the robber, killing him, police said. Police initially said the robber was possibly in his 40s.

Police said the shooter has a valid concealed carry license and a valid firearm owner’s identification card.

Concealed carry is increasing in Illinois as it is virtually everywhere else.

The greatest fear of gun control supporters in urban areas is that their citizens will see more stories like this that undermine the false narrative that “guns cause crime.”

Guns do not “cause” anything. Firearms are tools, and can be used for good or ill or utterly benign purposes, based upon the intent of the human user.

Criminals use tools to force their will upon others. Good people can use their same tools to resist evil.

The greatest fear of government is that the citizenry will discover this fact.

They craft lies to conceal this truth.

Don’t take their claims at face value. Do your own research, and arrive at your own conclusions.
