Ben Levi,
The US is far from the most dangerous country in the world. Here are some homicide rates from 2016, per 100,000 people.
US 5.4
Mexico 19.3
Guatemala 27.3
El Salvador 83.1
Belize 37.6
Honduras 56.5
Nicaragua 7.4
Costa Rica 11.9
Panama 10.0
Columbia 25. 5
Venezuela 56.3
Jamaica 47.0
Bahamas 28.4
Brazil 29.7
South Africa 34
Central African Republic 19.8
Philippines 11.0
Afghanistan 6.6
Mongolia 5.7
Russia 11.0
OTOH most of the rest of the free world has much lower homicide rates:
Canada 1.7
United Kingdom 1.2
Ireland 0.8
France 1.4
Germany 1.2
Spain 0.6
Italy 0.7
India 3.2
Pakistan 4.0
China 0.6
Korea 0.7
Japan 0.3
Most homicides are not from mass shootings.
And in many of these countries, including the US, suicides are far more common than homicides.
