Mexicans protest dog detentions, tests negative - Article Photos 4/9

Police officers take notes in front of cages where dogs caught near the site of four fatal maulings are being held at a city dog pound in Mexico City, Wednesday, Jan. 9, 2013. Authorities have captured dozens of dogs near the scene of the attacks in the capital's poor Iztapalapa district, but rather than calm residents, photos of the forlorn dogs brought a wave of sympathy for the animals, doubts about their involvement in the killings and debate about government handling of the stray dog problem.
