I've always been baffled and fascinated by this "prohibition" era in the USA between 1920 and 1933. That's 13 years!
I know very well about the concept of "speakeasy" clubs, that is, illegal bars. These were physical locations (obviously), allegedly available "in every corner".
How did the authorities somehow not find these? All it would take would be one pissed off customer, who gets angry at the bar keeper for any reason, such as not getting another drink on credit or something, to just go straight to the cops and tell them about the exact location. BAM! Raid. Speakeasy club shut down. Owner in jail. No more speakeasy bar on that physical location.
Yet, somehow, this didn't happen. They were apparently able to simultaneously run an illegal, physical bar in a crowded area, and have people obviously know about this since they must have customers, yet at the same time remain invisible to the cops.
This just does not add up to me. It doesn't make sense. After all, we aren't talking about some modern Tor .onion address hosted in some data center in Russia, or a sketchy mail-order business with some anonymously paid post box. We are talking about a physical, concrete location with an entrance and people standing inside it to accept orders and a stock of illegal alcohol that has to be regularly delivered there without anyone seeing it.
Even if every customer was treated like a king, and thus had no reason to "tell on them", the cops could simply go around and check every basement door in every block in the city and it'd take at most a few days (if they were very inefficient). That is, if their intention was to uphold this nation-wide law, which I assume they wanted since it existed in the first place.
Unless the authorities were actually "in on it", I basically don't even believe that such "speakeasy" clubs could have existed. Or I'm missing something critical about this world.
