The term "Black Friday" came out of the old Philadelphia Police Department's traffic squad. In 1961, the cops used it to describe the worst traffic jams which annually occurred in Center City on the Friday after Thanksgiving.
It was the day that Santa Claus took his chair in the department stores and every kid in the city wanted to see him. It was the first day of the Christmas shopping season. Schools were closed. Late in the day, out-of-town visitors began arriving for the Army-Navy football game.
Every "Black Friday," no police officer was permitted to take the day off. The division was placed on 12 hours of duty, and even the police band was ordered to Center City. It was not unusual to see a trombone player directing traffic.
Two officers were assigned to intersections along Market Street to control the throngs of pedestrians.
The department also placed police officers outside parking garages because the "lot filled" signs failed to deter motorists from lining up on the curb lane outside the garage. This reduced street size from two lanes to one. This caused traffic to back up and block traffic at the next intersection. This caused massive gridlock.
What started in Philadelphia son spread across the nation to give us the chaos we have today across the nation.
There are those on the liberal left with political agenda's that arenow trying to create new chaos by trying to tie Black Friday to slavery. They state that slaves were sold on Fridays and that all slaves were black; hence "Black Friday". Unfortunately the barbaric practice of selling slaves occurred on different days of the week and slavery included other races including white Irish men and women. It depended upon when the ships carrying the kidnapped people arrived.
There is no truth that Black Friday of today had anything to do with the selling of slaves in the past.
