Tactical Operations is a Beverly Hills gun store specializing in modified Remington 700 rifles. The bit of their website that hawks Tac-Ops training is suspiciously vague. “Tac-Ops training is conducted by a diverse group of highly experienced instructors with extensive real-world experience. Our instructors are drawn from the elite of the military and law enforcement special operations community — professionals who are currently operational both here and abroad.” And unnamed. “For security purposes, instructors cannot be identified outside of military or law enforcement circles.” The site also mentions, but doesn’t show, Silencers-Suppressors. Which brings us to Washington Wizards’ felonious Gilbert Arenas, recently convicted for bringing a bag o’ guns to the Verizon Center . . .
