There's a movie called Holocaust starring Meryl Streep that's very good. It's a very long movie and is the story of the Weis family and what happened to them and during the Holocaust. I don't want to tell everything about the movie but it does show what happened to the disabled in the film.
I checked on Amazon and the movie is expensive about $50 right now. If you're interested maybe your local library can get it for you.
I'll check that out. Thanks for the tip!
