Switzerland has a stunningly high rate of gun ownership — here's why it doesn't have mass shootings

• Switzerland hasn't had a mass shooting in 22 years.
• In the US, there is almost one every day, most recently in Lewiston, Maine.
• The Swiss have strict rules for who can get a gun, and take firearm training very seriously. 

Switzerland hasn't had a mass shooting since 2001, when a man stormed the local parliament in Zug, killing 14 people and then himself.

The country has about 2 million privately owned guns in a nation of 8.3 million people. In 2016, the country had 47 attempted homicides with firearms. The country's overall murder rate is near zero.
