Holocaust Reaction

No doubt there are many websites dedicated to the holocaust. This week I will attempt to write reactions to a few.
The following link is of Polish children at Auschwitz. My first reaction is sorrow obviously but once that is confusion as to why the guards forced them to stay behind the barbed wire and not let them go free.

I like this next link because the first part. The history of The Swastika is actually pretty interesting. Like I didn't know that it became the official symbol for Nazi's in 1920.
