The "Massive" SS agents don't ring true.
Well, maybe they were, compared to the waiters and diners.
I saw a pair of them one time escorting Janet Reno walking on Shelter Island in San Diego. They were small and unobtrusive and it didn't even occur to me that they were SS until long after they had walked past. They don't try to look like muscle. But I wouldn't want to show up on their radar as a threat!
Reno smiled at our kids.
