Murder rates go up and down. Like the climate. London, Europe, Asia all got "fixed" by the plague. Later the "Spanish" flu again reduced the world population density. Now we have screamed past 7 billion, and I figure we are going to get another plague or something to adjust the population densities again. (Notice the "Spanish" flu was a result of the war shipping soldiers all over)
In the mean time, all of North Africa is popping off. And then there is the Crimea / Ukraine. I am expecting another world war.
Honduras and Jamaica are not racist, they are the edge of the drug wars, with dealers and high crime rates. Because drugs come from down south a lot, where they are grown (cocaine, pot).
Drugs come from Afghanistan and the surrounding area (opium), and the jihadists in that area are big time into the drug trade.
Yes, I am saying that a great deal of violence is tied to drugs. This is true in the US as well as everywhere else.
London had a high murder rate, and a high population density of poor people (slums).
I personally recently was driving around a huge Central American city (Guadalajara, 8 mill), and poor people in the slums were walking around the streets with hammers looking for cars driving thru to rob (hammers are far cheaper than guns, legal, and easier to get). Scary.
England has for a very long time ad a much higher crime rate, and many say that it is because gun laws mean people cannot protect themselves (only criminals have guns). Now that terrorists use big knives, it is getting crazy.
Poor people have far more crime in their areas, at least partially because law enforcement does not want to go into dangerous areas, and partially because law enforcement does not give a shit about poor people. Maybe also there is some racial prejudice in law enforcement. For sure there are a lot of poor people without jobs looking to make a buck.
But in the US, the vast majority of criminals are drunks and druggies (at least according to the criminals). Messed up people.
I am very familiar with the poor, We were dirt poor when I was a kid. We lived in someone's one-car garage.
I am very familiar with druggies and alcoholics - I have 29 years clean and sober.
I am very familiar with cops gone bad - I was in witness protection against killer cops.
I am just not that familiar with racism - I am a white male.
