I have very mixed feelings on this topic.
Let me start by saying that I believe that in the US, decreasing policing has very catastrophic results because we're dealing with violent citizens and a violence-glorifying society. Unfortunately, whenever the justice system shows recession, minorities tend to attain more privilege and confidence in breaking the law. The perfect example would be in populist Mayor Dinkins of NYC in the late 80's and early 90's, and his recent reincarnation in Mayor DeBlasio. DeBlasio made away with the "Stop and Frisk" law which had New Yorkers feeling safer than ever. Now we find our selves feeling more vulnerable than ever and every "strapped" mauro gets to walk around with any weapon they please. Violent crime is on the rise, and in general the quality of life isn't what it was in New York City the last years, as DeBlasio has created an atmosphere of hatred and restrictions towards the NYPD. Landlords are increasingly at the mercy of minority tenants who abuse the system, while DeBlasio attempts to take away ALL landlord rights to their own property. The lunatics are trying to run the asylum, is pretty much what is starting to happen.
On the other side of the issue however, the US justice system is run like a third world, corrupt, business. You can't have a civilized nation that has a privately run prison system, funded by the ultra rich, which has to reach QUOTAS. Yes, QUOTAS. Meaning that if hypothetically, if crime were to decrease, they would still have to find ways to fill up prisons, in order to filter tax payer money into private pockets. They make deals with the state, that include provisions like "must maintain 90% occupancy."
The violent hip-hop/ gangsta rap industry gets the biggest boost from the media. Why? Because its a superior art form? No. Because the same companies that are heavily invested in media are also heavily invested in the prison system. Crime goes down, you pay some talentless idiots to make some raps songs glorifying gang wars, prison, drugs, and crime, and you're back in business.
Which brings me to my next issue. The war on drugs and the criminalization of marijuana. They've criminalized a substance FARRRRR less dangerous than alcohol, not nearly as addictive as nicotine, and kept it in the hands of violent blacks and hispanic gangs, all so that they can fill up their prisons. Tobacco gives off radioactive Polonium 210 when burned (not additive related but a natural result of burning the leaf), but an herb that relieves headaches, arthritis, glaucoma, epileptic seizures, anxiety, Alzheimer, multiple sclerosis, etc. is deemed too catastrophic. You legalize weed and the private prison system,the DEA, the justice system, and the pharma companies take a big hit.
Its not a matter of color or emotion. Its a matter of money. Jordan, the most famous and loved name in the black community is also invested in the prison system. As seen in the video, you give black people a free shirt and their doing cart wheels, show them some money, glorify crime, and you see the results. Same goes for whites, but when whites get arrested skin color is never an issue. A white guy who robs a bank, can go to jail for decades, but a stock broker can rob thousands of people and get away with a few months of time.
