Here's some google translated details on the new laws, nothing but clickb8 articles in english:
"Under the new rules, the following criteria are established for the citizen to prove "effective necessity" to possess a weapon at home:
To be a public agent (active or inactive) of categories such as: security agents, official of the Brazilian Intelligence Agency (Abin), penitentiary agents, socio-educational system employees and administrative police workers;
Being military (active or inactive)
Live in a rural area ;
Residing in urban areas of states with annual indexes of more than ten homicides per one hundred thousand inhabitants, according to data from 2016 presented in the Atlas of Violence 2018 (all states and the Federal District fit this criterion).
To be owner or legal guardian of commercial or industrial establishments ;
Be a collector, sniper and hunter, duly registered in the Army Command.
In addition, people who want to have a gun at home will need to obey the following requirement:
Check that there is a safe or safe place for storage in homes where children, adolescents or people with mental disabilities live;
The new decree maintains unchanged requirements already in force on possession of weapons, such as:
Mandatory courses to handle the weapon;
Be at least 25 years old ;
Have legal occupation ;
Not responding to police investigation or criminal prosecution ;
Do not have criminal records in the Federal, State (including courts), Military and Electoral Justices;"
He also upped the gun limit up from 2 to 4, and doubled the amount of time before you need to re-test. You can't get a gun unless the federal police authorizes you, but from the sound of the article and Bolsonaro's policies, you shouldn't have too much trouble getting one unless you're considered a criminal. No changes to caliber laws, so hues are still stuck with shitty .38 Tauruses.
