Here's the thing: In Switzerland, from 1848 until 1998, gun laws were in the hands of the Cantons (= States). 60% of the cantons had Vermont-style laws - you could carry ANY gun (handgun, shotgun, assault rifle...), open or concealed, WITHOUT A PERMIT. In the other cantons, you needed a permit for carrying, but it was easy to get.
Our violent crime rate was close to non-existent. We had a ridiculously low homicide rate.
During the 1990s, we experienced mass immigration from ex-Yugoslavia; close to 500'000 Croatians, Serbs and especially Albanians moved here (our population is now close to 8 million).
That caused a yearly increase in violent crime of about 1%, mostly the ex-Yugoslavs their war.So
In 1999, a new federal law went into effect. The ONLY reason it was passed was to be Schengen and EU conform. This law made gun carry illegal.
Most people believed that this would have absolutely no effect, as "Switzerland was a safe country, no one needed a gun".
In 1999, we experienced a 15% increase in violent crime.
Since then, our violent crime rate has risen by 600% and homicides DOUBLED!
We are still safer than our neighbors France, Germany, Austria and Italy, but our numbers have caught up. Fortunately, we are still far away from the numbers in the UK, which enacted a total gun ban in 1996!
This evolution is EXACTLY what I predicted before the passage of the new law. I was heavily lobbying for a referendum against he the law, but very few people were receptive to the argument that abolishing our gun carry right would lead to more violent crime.
Now the damage is done: close to 500 people died needlessly (the 100% increased homicide rate) and we no longer feel safe.
Criminal gangs invade Switzerland from France and Italy, mostly, to commit violent crimes here, because they no longer fear the threat of armed citizens and they don't give a flying sh** about the police.
So be careful before you think "It's safe to give up our guns now".
When you do, crime will be back - with a vengeance!
