Wonder if this has anything to do with it?
https://newstalk1130.iheart.com/featured/common-sense-central/content/2018-02-21-what-brazil-can-teach-america-about-gun-control/In the wake of last week's mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, gun control advocates have pushed for America to toughen its gun laws to bring them more in line with those in other developed nations.
Such advocates need look no further than Brazil, a nation that is generally comparable to the United States in both population (326 million people in the U.S., 210 million in Brazil) and economic status (The U.S. has the world's largest economy, Brazil has the eighth largest).
Yet the two nations differ in one key aspect--their treatment of guns.
In Brazil, no one under the age of 25 is allowed to own a firearm. Firearm registration is mandatory. The "carrying of firearms throughout the national territory is prohibited," except for "members of the Armed Forces," members of the municipal guards" of Brazil's states and largest municipalities, members of the police forces...prison officers and guards," and "members of private security and securities transport companies set up pursuant to" Law 10.826, Brazil's 2003 gun law.
This effectively means that no private citizens can legally carry their guns outside of their homes. And just to keep a gun in a private citizen's home, he or she must purchase a relatively expensive gun license, register it with local authorities, and pay a fee every three years to keep that license current.
In 2005, the Brazilian government cracked down even further--seizing firearms from citizens whom it determined did not need to own them. As Brazil's Agência Câmara reported:
The current disarmament campaign, begun May 6, has already collected some 5,000 weapons. To authorize the possession of a weapon, [the Government] developed a strict interpretation of the concept of "effective necessity." For example, long-barreled weapons are denied for those who live in the city, nor is anyone authorized to possess a registered weapon.
