I went over to the guy, who looked to be in his early 60s and projected the aura of a man who’d spent his adult life in policing. I asked what he thought of the show. He shook his head slowly and raised his eyes to the heavens. “It’s ridiculous,” he said. “It’s the most expensive candy store on earth for my guys. And, between you and me, there’s nobody on earth more gullible than rookie cops. They want everything they see—armored vehicles and battering rams and sniper rifles. I tell them, ‘Guys, guys, listen to me. Everything you need to do your job was invented 50 years ago. Sidearm, shotgun, tear gas, night stick, and handcuffs. The best piece of equipment you’ve got is up here,’” he said, tapping the side of his head.
