Mexican anti-riot police arrest a colleague May 8. Hundreds of disgruntled Mexican police battled with anti-riot squads using rocks and bottles. News reports said dozens were injured and at last 17 were arrested. The protest is against a controversial plan to give the police force military training, while soldiers dressed as policemen manned the streets on a rotational district-by-district basis. gm/ Photo by Heriberto Rodriguez..
