How did Hitler choose which people to go on which side of the Berlin wall?
Hitler was already dead at the time. No one chose who went
where, where you were when they decided on the divide was where you
lived. For example: say you went across where the wall was going to
be for shopping or something and when you got back it had been
decided that the wall would go up, even if you could see your house
from where you were you would be forced to stay on that side.
