What I don't understand is why cops don't spin this to their favor.
Say
With all the money we save by legalizing drugs, we can hire more cops and give them better technology to better enforce laws that matter. Common math easily shows how every 2 prisoners costs the same as a typical police officer.
That's not how prohibition works. During alcohol prohibition, organized crime went through the roof. It was like current gang warfare but it was with alcohol instead of coke/heroin/other. During that surge of organized crime, there had to be more police. Keeping drugs illegal drives up the demand for police and security forces. Right now the US has an entire federal agency devoted to current drug prohibition (DEA).
If all drugs were suddenly legalized and a company like Bayer made a billion dollar cocaine factory that could produce stuff that was better, cheaper, and safer, then organized crime would fall flat on its face and need to find some other way to make money. Thousands of police would eventually be let go. Prison guards would be let go. Lawyers would be let go. The whole justice system would shrink. Instead of arresting 20 people for doing cocaine, they would only arrest the 1 guy who freaks out and stabs someone while high on cocaine. They would only arrest the 1 pothead who.... sits on his couch all day and refuses to get a job because that's like being part of the system, man.
It's worth noting that studies have mixed conclusions about whether or not alcohol prohibition actually worked. On one hand, really up tight people who would never smoke a joint or do a line would stay away from alcohol just because it was illegal. The other side is that making it illegal made it cool because it was rebellious (example: underage drinking is
still super cool). People who had alcohol problems were not able to get help. If you want to stop a legal drug like nicotine, you go buy a nicotine patch and try your best. If you want to stop something illegal like heroin, there's no patch or gum to buy and people won't help you; you'll probably just die on the street or something.
