A citizens’ group in the Bicol Region has thrown its support behind any investigation that the Senate would undertake into the social cost of the presence of US troops in the country, as well as its adverse effects on the local community. This statement of support by the Bikolano Alliance for Nationalism Against Balikatan (BAN Balikatan) came on the heels of Sen. Francis “Kiko” Pangilinan’s call for an investigation into reports that US soldiers participating in the Balikatan military exercises in Bicol are enjoying nightly prostitution “services”.
