More on Brazil, from the BBC
The BBC summary of the Brazilian referendum is ... strangely suggestive of US debates on the gun issue.
The antis campaign " was heavy in celebrity razzamatazz, and light in penetrating argument." Its political sponsors were dealing with accusations of official corruption. When the opposing campaign heated up, many started waffling.
The pro-gun side "portrayed the referendum in terms of civil rights, claiming that the government wanted to take away the right of people to choose how best to defend themselves," and argued that "criminals do not buy guns legally in shops, where customers are subject to strict background checks." The net result, they submitted, was that the law would not disarm criminals, but would stop honest citizens from defending against them.
I think I've seen this debate somewhere before...
