Not to defend the killers in Chicago, but most of those ae gang related shootings. Like the St. Valentine’s Day massacre. All business.
Manson, however, sent his people to butcher (literally) the victims.
No, check the statistics. Many or most of the killers may be gang members... but its nothing like the “St. Valentine's Day Massacre”. It is not the mafia and it is not about business. Let's not romanticize the motives of the Manson people vs. other killers. It is mostly all just evil people killing other people... In most cases their victims were just in the wrong place at the wrong time.
When I was working as a firefighter in the early 1990s part of our town was considered one of the most dangerous places on the West Coast. One night I hopped out of bed in the middle of the night to tell the other guys to turn the TV down. They were all laying on the floor. The shooting I thought was from a war movie was going on in the front and side yard of the station. We even ended up with a couple of broken windows.
These clowns weren't shooting at each other because of business, money, or even drugs. It was all straight stupidity and evil and most of their victims were just innocent people that got in the way.
That station was known as the gun and knife club. You could count on seeing at least a couple stabbings and shootings or both every time you went to work. We even had people coming in from out of the area to do ride-alongs to get experience. Thank goodness it finally cleared up.
I spent 25 years working as a firefighter. I saw many horrific scenes which resulted from the evil actions of evil people. Manson and has followers caught the imagination of Hollywood and the public. But there are many others who have the same type of evil lurking within them.
