Celaya police chief Jesús Rivera said three police officers had been wounded, but their injuries did not appear to be life-threatening.Earlier this month, nine people were killed, including waitresses, after gunmen burst into a bar and opened fire in the violence-wracked state.Last month , a dozen people, six of them women, were killed in an attack on a bar in another Guanajuato city.The Department of Justice considers the Jalisco cartel to be "one of the five most dangerous transnational criminal organizations in the world.""Those cartels are acting with calculated, deliberate treachery to get fentanyl to the United States and to get people to buy it through fake pills, by hiding it in other drugs, any means that they can take in order to drive addiction and to make money," DEA Administrator Anne Milgram told "CBS Mornings.""
