In Mexico, a country plagued by drug cartel violence, the mayor of the capital city is offering residents cash, new bikes and computers in exchange for their guns. He says the buyback program will get dangerous weapons out of the hands of residents and make the streets safer.
But not all mayors in Mexico — where it's extremely difficult to legally buy a gun — are rushing to replicate the program. In fact, in cities overrun by drug traffickers, some say law-abiding citizens should be able to have them for protection.
It has been a busy year in Mexico's war on drugs. The administration of former President Felipe Calderon struck major blows to the country's largest cartels, slowing the violence that has claimed more than 50,000 lives.
But the new president, Enrique Pena Nieto, says he'll change tactics. He wants to go after the crime associated with drug trafficking instead of taking down crime bosses. His new attorney general says this is the right strategy, since the number of crime gangs working in the country has grown significantly.
Now, U.S. Customs and Border Protection agents say they recently discovered 30 large cans of marijuana in a field near Yuma, Ariz., — and that the barrels apparently landed there after being fired from a pneumatic-powered cannon 500 feet away in Mexico.
