A dozen or so charred vehicles sit in a government impound lot outside this northwestern city including a patrol car, a military pickup and a tractor-trailer, casualties of a recent terrifying shootout between drug gang henchmen and Mexican security forces. In a central district where the worst of the violence took place, blown-out windows have been replaced and bullet holes are plastered over on restaurants, convenience stores and a home where the son of Mexico’s notorious drug lord was believed to have been holed up.
