RIO DE JANEIRO —
Other officials, however, rejected any relaxation of the laws.
"The more weapons allowed to circulate, the more weapons will wind up in the wrong hands," said Jose Vicente da Silva, Brazil's former public safety secretary. "There must be restrictions, because most weapons now in the hands of criminals were once legal and became illegal when stolen."
Guaracy Mingardi, a security expert at the University of Sao Paulo, said the only way to prevent killings like the one in Rio is to "clamp down on the access to weapons."
"We cannot put policemen on every street corner, or armed guards inside every school," he said. "Things like metal detectors or security cameras are not difficult to bypass by someone who wants to get a weapon inside the school. They will always find a way."
