If the girl has a speech impediment (which was reported on a radio station this am), the she isn't slow or mentally retarded, imo. And this issue is another of many about this sickening situation that ticks me off. Just because someone studders, let's say, doesn't mean they are retarded or slow. So for the news source to say she's developmentally disabled when in fact she has speech difficulties is like calling a cow a cat.
Do we ever expect newspapers to get anything right?
