Fortunately (and it's painful to acknowledge this because they're human beings that chose the wrong path), death squads have been doing their thing. The gangs aren't as powerful as they had been as a result. Venezuela is mirroring many things that have happened in Russia in this regard.

Many average male Venezuelans have had a bad experience with crime.

The lonely petty thief looking for trouble is a Darwinian specimen that won't last for too long. Once he (or even she) is detected stealing from someone (they will use the gun to punch if the victim paralyzes or refuses to cooperate), chances are that some witnesses would run over them with a car and get out of dodge.

The victims will collect their valuables and hit the road. Everything ends there. This isn't common, but it happens. Some examples of this have been caught on film. I have watched a few, and the social media crowd cheered up the anonymous heroes. Go figure.
