This week brought us two more mass shootings, in two very different countries.

The 308th mass shooting in the United States this year occurred on the 4th of July, when a gunman opened fire on a crowd gathered for an Independence Day parade in the Chicago suburb of Highland Park. Bobby Crimo III has been charged with seven counts of murder. 36 people were injured in the incident. 

In a separate incident in Copenhagen, a man opened fire on a crowd in one of the biggest shopping malls in Scandinavia, despite Denmark having some of the strictest gun laws in the world. Three were killed and four more injured. In total, 30 people were hurt in a subsequent stampede.

“Our beautiful and usually so safe capital was changed in a split second,” Danish Prime Minister, Mette Frederiksen, said. The attack has been ruled out as an “act of terrorism” by Danish police. It was the first shooting of this kind in Denmark since February 2015.

So this may have you wondering… how much of an impact do gun laws have on deterring mass shootings?

The Denmark shooting was isolated and the fact that it was their first in almost 30 years says everything that needs to be said of the efficacy of their gun laws. America’s gun culture and the constitutional right to bear arms, laid out in the Second Amendment, is a key driver behind their contagion of mass shootings. 

Better gun laws won’t eliminate mass shootings entirely and the incident in Copenhagen is evidence of that. But it’s the frequency at which they happen in the states that provides all the evidence we need to see that gun reform is imperative to prevent more needless deaths.
