If local, state and federal officials can't track down and apprehend those responsible, they decided they'll take matters into their own hands.
"We are going to have to rise up with weapons. ... We cannot wait until they keep destroying the port of Acapulco with these kinds of incidents," said Sergio Mejia, president of a 35-member association of restaurant and business owners in Acapulco's Bonfil beach community. "We think the government is very timid, very slow. If there is no immediate response, it leaves us no choice but to join the fight and set up checkpoints on the street corners."
Months ago, he read about other groups in the region taking similar steps, forming paramilitary self-defense groups of masked men that patrol the streets. At first, it seemed extreme. Now, it sounds sensible, he said.
In this area where the economy relies on tourism, he said, residents are tired of waiting for authorities to take action. But it's not just that a high-profile crime targeting tourists is bad for business.
"Today they were foreigners," said Mejia, who owns a restaurant that specializes in serving up freshly caught seafood. "Tomorrow it could be our families."
Guerrero is named for a military general who fought for Mexico's independence from Spain. It's also the Spanish word for warrior.
If the government can't protect them, Mejia says it's time for the state's residents to fight back.
