One itty-bitty problem with your hypothesis...the "elderly people" CHOSE to attend and are self-sufficient and can find their own way home.
Additionally, the President didn't leave anyone in the cold.
Furthermore, they aren't dogs or pets, they are people.
Additionally, only NAZI's report their neighbors to the authorities.
Me, I knock on my neighbors door and tell him to his face if I have a problem with his actions...I don't go whining and crying to a cop. They have better things to do.
