One guy on here went with,"Why did cripple guy not understand the world as I would, I pretended I was him and it's not a problem." There is a lot missing without one of the inputs. Humans communicate on a spectrum of bands. Missing one causes confusion and miscommunication.
I've had a handful of encounters with police. I've been stopped for being drunk (I wasn't, just blind and hadn't been willing to use the stick yet.) I could tell he, the cop, was uncomfortable with me. I dropped my ID, told him I couldn't see and asked for help. No idea his response, but he was silent as I crawled around on my hands and knees looking for my ID he was demanding.
I don't know how far this was, or the other cops were, from violence when they stopped and interacted with me. But I could feel the mistrust. I'm confident they were thinking about it. Because I don't behave like everyone else.
This is entirely predictable, and I imagine, common. It's also a thing I fear whenever I'm aware I'm near a cop.
