In addition to being a fan of concealed weapons laws, Alderman Charles Quincy Troupe has also made no attempt to disguise his animosity for Mayor Francis Slay.

Now, it seems, Slay is returning the favor.

After Troupe’s firearms push made news last week — the north St. Louis alderman has lost faith in the city police and wishes more of his law-abiding constituents would get gun permits — Slay took the opportunity to question whether the effort was more about politics than public safety.

This weekend, after returning from a memorial for a rookie cop killed on duty last year, Slay got in another jab at Troupe.

“When a St. Louis alderman suggested last week that St. Louis police officers might not care about the City neighborhoods in which they patrol, it is unlikely that he was thinking of Police Officer Norvelle Brown,” Slay wrote on his website. “Norvelle Brown was an armed, trained, on-duty police officer murdered last year by a teenager using a handgun given to him by another teenager.”

Slay spoke Saturday at the Wohl rec center, where a monument was dedicated in Brown’s honor.

“I used the sad occasion of the ceremony,” Slay wrote later, “to urge St. Louisans to make every effort to get handguns off our streets.”

Including, it would seem, Alderman Troupe.
