Seems like everybody in the NYPD is doing it.
And so what? The whole concept is strange to this former Baltimore police officer. So is the language.
I had three real badges when I was cop. They give you one, for your shirt or jacket. You need to pay for others. One other you need, for the wallet. I also got one more, one suitable for framing, a so-called plaque badge. The wallet badge is also a plaque badge (flat) with the pins cut and filed off. When I quit, I turned one of them in. You do the math.
But cops know that the badge isn't the big deal. It's the "credentials" that matter. I had but one of those. And I turned it in like a good boy.
