I'm 99% sure that you're kidding, but a shitload of people actually think like that. Decades of copaganda in TV and movies weren't for nothing, and now social media is full of it. The 80s was saturated with loose cannon cops who get results and it convinced people that sometimes it's okay to violate rights. Now it's cops doing tiktok dances or flipping water bottles to convince people that hey, they're regular people just like me, and well, golly gee, I'm not a fascist so how can I possibly believe that they're fascists?

Have one involuntary interaction with a cop and your view will change. The cops primarily target brown and/or poor people, so it's no wonder that the vast majority of thin blue line dipshits are financially comfortable honkies who've never had the cops target them.

Sidenote: I've always chuckled at the people who have both a thin blue line bumper sticker and Gadsden flag bumper stick/license plate. Basically a billboard that says "tread on those ones, officers" but they're always the same people claiming "I don't have a racist bone in my body!" Okay, but only because bones can't be racist; it's your brain that's racist.
