The crime situation was particularly bad in Brazil when Jair Bolsonaro entered office. Brazil had one of the highest homicide rates in the developed world, with 27.8 homicides per 100,000 people. (In the United States, the same figure is 5 per 100,000 people.) Around 70 per cent of homicides were committed with firearms.

The Bolsonaro government quickly moved to make no less than 32 changes to Brazilian gun laws, including simplifying the background screening procedure, legalising the purchase of more powerful guns, reducing licensing costs, deregulating gun carry and increasing the legal maximum of purchasable ammunition one hundredfold (!). As a result, gun ownership boomed in Brazil. The number of licensed, legally purchased guns more than doubled after Bolsonaro’s reforms.

Results? The homicide rate has fallen by 34 per cent, to 18.5 homicides per 100,000 people in the past three years.
