Armed militants a potentially menacing wild card in Venezuela.

Carlos Torres opens the wire-fence gate to a neighborhood controlled by the La Piedrita gang that even police don't enter without permission.

"Loyal to Comandante Chavez" reads a banner beside the gate reads a banner just inside the 23 of January redoubt in western Caracas. The poor neighborhood is home to a small army of pistol-toting young men who, like Torres, see themselves as guardians of President Hugo Chavez's "socialist revolution."

These die-hard Chavistas say there is no way they will let Venezuela's "oligarchy" and its alleged Washington patrons to return to power.

"That would cost us blood, sweat and tears, but they won't be back," he said.

If Chavez's populist system is indeed threatened by domestic and foreign foes as his anointed successor claims, this is the defense. On alert and, in many cases on edge, are hundreds of well-armed toughs who belong to such shadowy "collectives" as La Piedrita, which have been blamed for strong-armed intimidation of political opponents and worse.

For such Chavez supporters, Monday's call by Communication Minister Ernesto Villegas' to be "on a war footing" was clearly heard.

They are the most visible face of an unknown number of armed cadres loyal to the government, groups unrelated to the 125,000-member national militia that is affiliated with the armed forces. As Venezuela ponders the next steps after Chavez's death Tuesday, the late leader's most uncompromising and radical supporters make up a menacing unknown in a country brimming with guns and afflicted by the world's second-highest murder rate.

What's especially dangerous, human rights and opposition activists say, is that Venezuela's law enforcement authorities generally leave them alone.

Vice President Nicolas Maduro, named by Chavez to be his socialist party's presidential candidate in elections should he die, has been claiming for weeks that opposition leader Henrique Capriles has been "conspiring" against Venezuelan democracy.

Over the weekend, and then just hours before he announced Chavez's death, Maduro claimed Capriles was plotting with far-right U.S. putschists and "fugitive bankers" against the government.

Chavez himself long used just such tactics and rhetoric. Opponents said he stoked xenophobia while letting his lieutenants turn their partisans into armed, quickly deployable civilian shock troops.

Maduro also expelled two U.S. military attaches for allegedly trying to recruit Venezuelan officers for "destabilizing projects," proof enough for Torres that Washington, the chief importer of Venezuelan crude oil, is trying to sabotage the revolution.

"The CIA is trained in this sort of thing. It has contributed to the toppling of governments and spilled blood in Central America and South America," he said.

"But they will be up against the people here. Just let them try to meddle and there won't be another drop of oil for the United States."

La Piedrita and a group known as the Tupamaros were around long before Chavez first took office in 1999. They form part of an estimated 1,000 to 1,500 "colectivistas" who live within eight miles (12 kilometers) of the Miraflores Presidential Palace, says Rocio San Miguel of the non-governmental watchdog group Control Ciudadano.

Under Chavez, both bands grew while other motorcycle-circulating toughs arose, all loyal to the charismatic former paratrooper.

While such groups perform community service projects, painting buildings, repairing elevators and cleaning streets, some have been videotaped flashing weapons in public. Gang members have also been recorded committing crimes, only to disappear into their protected territories, stymieing police pursuit.

"There is something of a tacit agreement that the police don't enter," said Luis Izquiel, a criminal lawyer who coordinates the security commission of the MUD opposition coalition.

There is no proof such groups receive arms and training from the government, though some government critics accuse officials of funneling weapons to them.

The country is swimming in what the government has estimated are about 6 million firearms, some 90 percent of them illegal. It is unclear how much of Venezuela's violent crime is politically motivated, how much financially.

"What is certain is that the collectives have for years had military-grade weapons and have committed some crimes with complete impunity and it appears this has happened under the complicit view of government authorities," Izquiel said.

Pro-Chavista collectives can vary, of course, in their zealousness.

Jesus Bermudez rode in a pickup truck with four black-bereted militants of the Tupamaros collective Wednesday amid the massive outpouring of grief that filled Chavez's funeral cortege through central Caracas.

"We have an enemy who will never rest. Nor will the revolutionaries rest," he said.

Bermudez didn't discount using violence to defend Chavismo, saying "the revolution can't just be about speech," but the 37-year-old added that if Capriles were to win snap elections expected to be called shortly, his group would respect the result.

Bermudez denied rumors the Tupamaros were among the masked men on motorcycles, some brandishing pistols, who had attacked about 40 students demanding details of Chavez's condition outside the country's Supreme Court. The attack on the students, who had chained themselves to lampposts, occurred at exactly the hour Maduro announced Chavez's death.

Militant and community organizer Raisa Urbina was waiting down the road from Bermudez Wednesday with some 20,000 mourners outside the Fort Tiuna military base where Chavez's coffin now lies in state.

Just before last October's presidential elections, Urbina had boasted to a reporter of leading a group of more than 300 people that she said was ready to take up arms to defend the revolution if Chavez were to lose. The tears on her cheeks may not have been for Chavez alone: Urbina's bald scalp attests to chemotherapy for late-stage breast cancer she is undergoing.

Urbina, 58, runs a mission for the poor called La Fortaleza just outside Caracas with a shrine to revolutionaries filled with the faces of leftist luminaries including Karl Marx, Fidel Castro, Che Guevara and Ho Chi Minh.

Urbina said she no longer believes Chavismo is under threat or that violence is needed, citing the Oct. 7 elections in which Capriles won 45 percent of the vote.

"We were fighting for our power and we won," said Urbina, dressed neck to boots in camouflage, a Chavez earring pinned on her left lobe.

She said she was also confident Maduro will be Venezuela's next elected president.

"Look out at the tribunal," she said, motioning toward a sea of Chavista-red shirts. "There's the answer, the people. This will last for years and will never be forgotten. Never."
