Venezuela, Crime and Poverty

I don't know whether to believe the story or not (It is an AP story) but if it is true does it say anything about poverty and crime and causality?

The feared street gangster El Negrito sleeps with a pistol under his pillow and says he’s lost track of his murder count. But despite his hardened demeanor, he’s quick to gripe about how Venezuela’s failing economy is cutting into his profits.
Firing a gun has become a luxury. Bullets are expensive at $1 each. And with less cash circulating on the street, he says robberies just don’t pay like they used to.
For the 24-year-old, that has all given way to a simple fact: Even for Venezuelan criminals it’s become harder to get by.
“If you empty your clip, you’re shooting off $15,” said El Negrito, who spoke to The Associated Press on the condition he be identified only by his street name and photographed wearing a hoodie and face mask to avoid attracting unwelcomed attention. “You lose your pistol or the police take it and you’re throwing away $800.”
In something of an unexpected silver lining to the country’s all-consuming economic crunch, experts say armed assaults and killings are plummeting in one of the world’s most violent nations. At the Venezuelan Observatory of Violence, a Caracas-based nonprofit group, researchers estimate homicides have plunged up to 20% over the last three years based on tallies from media clippings and sources at local morgues.
Officials of President Nicolás Maduro’s socialist administration have drawn criticism for not releasing robust crime statistics, but the government on Tuesday gave the AP figures showing a 39 percent drop in homicides over the same three-year period, with 10,598 killings in 2018. Officials also report a fall in kidnappings.
The decline has a direct link to the economic tailspin that has helped spark a political battle for control of the once-wealthy oil nation.

I once read a UK police official who said crime goes up when the economy is good because people drink more.

Some democrats used to contend that the way to reduce violence directed at the USA from the middle east was to stop buying petroleum, presumably so they would be so poor that they could not buy tickets to fly to the USA. BTW I never believed that idea and still do not.
