Cops REALLY need to take asl classes as an requirement so they won't mess or hurt other people when they don't even understand what they are saying! Hearing people think deaf people don't understand them but it's actually the other way around. They do not understand us. They do not understand what it is like to live as a deaf person and every deaf person have different rates of hearing, some can speak while some others can't but seriously, most of them do know sign language so it is best to learn sign language with them in case. Sigh, it appears that nobody really cares about how different the deaf culture is from their own preferred culture or whatever they call it.
