But how should be the solution look like? The laxness of the Brisola administration and other before created the problem of powerfull narco-gangs who terrorise the city.

Haven't governor Sergio Cabral and mayor Cécar Maya not won by promising to take the offensive to the narco-gangs?
And what responsabilty do the people of the favelas bear by tolerating gangs like Commando Vermelio and Amigos dos Amigos? do they have a choice at all? all of looks very much like hisbollah tactics to me: the drug lords provide little goods to the people who accept it, in return they can do their business unharmed by the people who live there.

But What about the middle class and working people from neighbourhoods such as Botafogo, Flamengo, Tijuca etc. who live in constant terror because its not the police who owns the firepower monopoly, but drug gangs who can kill whenever they want, whereever they want.
and that these people are killers must not be stressed here, it should be clear to everyone who knows rio a little bit. thay are rganized like little armies, with all the firepower they want.
look for example at the new years eve party in copacabana, where gang members shot into the crowds, and for what? http://www.youtube.com/watch?v=zC_GrZTrOk8. Yes 6 people got hit just on that very spot, how many others have been shot that day? But thats not only to be found on new years eve, in rio on average 4 people get hit every single day by so called "stray bullets"
. People who are in the shower, who are waiting in a line to catch the bus, who are in their beds, or like in the case of a boy, who was shot just some weeks ago playing football in leblon. his family just moved their, because they thought leblon would provide some security. too bad gang members from the favela "Chácara do Céu" were spraying bullets in the air, in direction of leblon.

i agree that pure force will never solve the problem, but the electorate has spoken, the people are tired of lax policies, they demand action. while this war against crime is felt most intensive, it isnt the whole story. other approaches are there. it is sad that rio has more to learn from the us military in iraq or the eu force in lebanon then from other places. but for now it seems that this is what it will be for the comming years. maybe people will have to think about taking the money machine away from the narco gangs, that would mean legalizing all drugs and selling them through state owend or lizenzed businesses. but until there, much talking must be done. and meanwhile we will watch the violence in tv.
