Хотя, вот что нашёл в путеводителе:
Резюме - если специально не ходить в т.н. фавелы, где живут самые нищие - шанс стать терпилой не выше, чем в другом крупном городе. К слову, у меня знакомого грабанули на улице в Нью Йорке, другого пытались в Женеве, а то всё Рио да Рио
SAFETY
Sometime in the 1980s Brazil began developing a world reputation
for violence and crime. Rio especially was seen as the sort of place
where walking down the street was openly asking for a mugging.
Some of this was pure sensationalism, but there was a good measure
of truth as well. Brazil at the time was massively in debt to First
World banks, and the combination of crippling interest payments
and International Monetary Fund austerity measures left governments
at all levels with no money for basics, such as street lighting
and police, much less schools and hospitals.
Fortunately, in the early ’90s things began to turn around. The
debt crisis eased, leaving governments with some discretionary
spending, and with the advent of the 1992 World Environment
Conference in Rio, Brazilians realized they had a serious image problem
on their hands. Governments began putting money back into
basic services, starting with policing. Cops were stationed on city
streets, on public beaches, and anywhere else there seemed to be a
problem. At the same time governments began working on extending
water and sanitation to some of the city’s poorer residents in the
favelas (shantytowns).
The decade-long expansion that followed made massive new
investments in tourism infrastructure feasible. Many cities got
brand-new airports. A domestic tourism boom ensued, making the
protection of tourists even more of a political imperative. Nowadays,
though still not perfect by any means, Rio, São Paulo, and Brazil’s
other big cities have bounced back to the point where they’re as safe
as some large international cities.
Statistically, of course, Rio and other big Brazilian cities still have
very high crime rates, including high rates of violent crime. Most of
that crime, however, takes place in the favelas of the far-off industrial
outskirts. Brazil is a highly unequal society and the burden of crime
and violence falls disproportionately (and unfairly) on the country’s
poor. But unless you go wandering unaccompanied into a hillside
favela (not recommended), you’re unlikely to be affected.
