OK, Here is my 2 cents
As a police officer, I receive information about "Violent" Crimes in this country as compared to other countries in world, quarterly. These are crimes that are "Reported". Based on the info., the United States is the "most" violent contry in the world. We do incarcerate more than others, that is "reported." The punishment for crimes in the United States is less severe than other countries. We have something called Probation and Parole which is not heard of in other countries. This allows for repeat offenders, which drives our crime stats up. Our judicial system is extremely slow compaired to other countries. Most definetly our jails are extremely more human than most.
Some countries require the families to support the family member incarcerated. If they dont, then he will probably die. We enjoy our freedoms and that comes with a cost. I cannot provide any stats of crimes committed against US Citizens versus Crimes committed against foreign tourist.
I will say this, I dont care what country you visit, Its not wise to piss off the police in countries outside of the US. The punishments are severe.
Have a good day
