What is to be done about US gun scourge?

If I had a magic wand, an immensely powerful magic wand, I would just wave it and make all the guns in the United States, my home country, disappear. Problem solved. Maybe.

In 2016, the State of Florida had 1,111 murders with a murder rate of 5.4 per 100,000 people, according to data from the US Federal Bureau of Investigation. The data is not broken down by county, but Miami-Dade County, which is nearby Parkland High School, has a murder rate of about 12 per 100,000. So with a total of 2,700,000 people, we can estimate that there are roughly 325 murders per year, 27 per month, in Miami-Dade. Sadly, the 17 students killed at Parkland will hardly make a blip in the murder statistics.

Other cities - Chicago, Washington, Baltimore - are even worse. In Baltimore, Maryland, just 50 kilometers from the nation's capital, there were 343 murders last year, in a city of only 620,000 people. That's a murder rate of 55 per 100,000.
