"President-elect Donald Trump has continued employing a private security and intelligence team at his victory rallies, and he is expected to keep at least some members of the team after he becomes president, according to people familiar with the plans.
"The arrangement represents a major break from tradition. All modern presidents and presidents-elect have entrusted their personal security entirely to the Secret Service, and their event security mostly to local law enforcement..."
Well, maybe a break from American tradition. But let's remember that leaders having private security forces have not been totally unknown:
"It began with a small guard unit known as the Saal-Schutz (Hall-Protection) made up of NSDAP volunteers to provide security for party meetings in Munich...
Three main SS groups were assigned to protect Hitler. In 1933, his larger personal bodyguard unit (previously the 1st SS-Standarte) was called to Berlin to replace the Army Chancellery Guard, assigned to protect the Chancellor of Germany"
And we know where that ended up. If you think it can't happen here, you obviously haven't been paying attention.
