Rock band 3 Doors Down (“Kryptonite”) headlined the Festival at the Switchyard in Carrollton, Texas last weekend, and lead guitarist Chris Henderson posted to Instagram a photo of his Paul Reed Smith guitar, which he’s turned into a tribute to fallen police officers.

Here is Twitchy’s coverage of the execution-style murder of Deputy Goforth, who was shot for no other reason than for wearing a uniform.

Speaking of uniforms, Henderson is a U.S. Navy veteran, and recently told AOL that most veterans he’s met have a “continuing drive to serve our country,” adding, “There is an honor among us that can’t be broken.”
