If there are lots of weapons, there will be more crime, but also an increase in defense & protection and a decrease in vulnerability.
The United States is full of extremely intelligent people which can have dangerous consequences. An increase in weapons technology is another step up in nature and it shows America’s power, brilliance, and intelligence. This will make the U.S. military undefeatable.
