PETARE, Venezuela - Stern-looking soldiers clutching assault rifles wave down the beat-up Chevy Caprice entering this sprawling slum on the outskirts of Caracas.
Flashlights in his face, the driver steps out and places his hands on the roof while the soldiers frisk him for drugs and weapons.
He's clean, and a hand gesture from the commanding officer sends him off into the maze of ramshackle homes that is Petare, one of the most dangerous parts of Venezuela's notoriously crime-infested capital.
Since Monday, this scene is playing out day and night at dozens of military checkpoints set up here in the socialist government's latest attempt to control the oil-rich country's pandemic of violence.
Critics dismiss the "Secure Homeland" initiative as a political charade that risks degenerating into human-rights abuses while having no lasting impact on crime. But to many residents, weary of being terrorized by armed gangs, seeing troops on the streets is a welcome projection of government power.
"You have to act forcefully so that people feel the force of the state," said Irving Garcia, 47, an unemployed former army reservist, who like many Caracas residents has firsthand experience of violent crime. Garcia said he was shot in the chest when he unknowingly walked into a restaurant robbery.
With about 15,000 killings a year, Venezuela's homicide rate is the fifth highest in the world, according to U.N. statistics. The murder rate doubled during the 14-year-rule of the late President Hugo Chavez, as cheap access to guns and an ineffective justice system fed a culture of violence in slums like Petare, parts of which have become no-go zones for outsiders, including police.
Chavez banned gun sales, expanded a new national police force, and stepped up policing and other programs in high-crime areas. Now, his handpicked successor, Nicolas Maduro, is adding military muscle by deploying 3,000 troops on the streets. The initiative started Monday in the Caracas area and will be expanded next week to the states of Zulia, Lara, and Carabobo.
Human-rights activists worry that sending soldiers trained for warfare on policing missions will only make things worse for the residents they are meant to protect.
"It's going to aggravate the situation, unfortunately, because the army isn't prepared to deal with issues of public safety," said Liliana Ortega, director of the COFAVIC human-rights group. "We have various emblematic cases in which the use of the armed forces resulted in disproportional force."
The soldiers, who work together with the National Guard and national police force, have the power to make arrests, but are supposed to hand over the detainees to civilian authorities. Any human-rights abuses would be tried by civilian courts, according to the constitution.
In deeply divided Venezuela, there are also concerns over the initiative's political undertones. Maduro narrowly won an April 14 presidential election that the opposition contends he stole through fraud, voter intimidation, and abuse of government powers. Some of the first military units were deployed in areas under the political control of the opposition.
Petare, for example, lies in Miranda state, which is governed by Henrique Capriles, Maduro's challenger in the presidential election.
David Smilde, a Venezuela expert at the University of Georgia, said that for Maduro, the security initiative was both "an effort to fight crime and an effort to maintain or recover support in places where it has been declining because of crime and violence, among other issues."
