NYC has one of the strictest laws in the world but that never stopped criminals.
Despite parts of NYC being literal islands, NYC is not figuratively an island. In other words, NYC can put as many strict laws into place that it wants, but guns can always be brought in from outside of the city.
yet the murder rate is very low, especially when factoring out terrorism, underworld hits and “family honor” killings.
While murders and mass shootings get almost all of the media attention in the U.S., the large majority of gun deaths here are a result of suicides.
America has a huge population so statistically there will be more people who go nuts. Also the mentality regarding violence is very important.
Not just a huge population, but a huge quantity of guns. There are likely more guns than people in the U.S., and the U.S. population is almost 310 million.
