Lula signs decree tightening Brazil's gun laws, reversing Bolsonaro's policies

Lula's decree reduces the number of guns civilians can legally own and limits ammunition purchases.
The decree bars civilians from owning 9mm pistols, restricting them to police and military.
It undoes the significant increase in legal gun ownership under previous president Bolsonaro.
The new rules encourage citizens to relinquish newly restricted guns or face confiscation.
The Federal Police becomes the watchdog over firearms, replacing the military in that role.
