By Amy Sawitta Lefevre BANGKOK (Reuters) - Anti-government protesters in Thailand pinned their hopes on winning support from the powerful security forces on Thursday as they push to oust Prime Minister Yingluck Shinawatra and install an unelected administration. A small group of protesters scaled the walls into the grounds of Yingluck's Government House office on Thursday but soon left without a confrontation with police stationed there. Protest leader Suthep Thaugsuban, a former deputy premier accused of murder during widespread 2010 protests, has asked police and military chiefs to meet him by Thursday evening and to choose their side in the latest crisis engulfing Southeast Asia's second-biggest economy. The politically powerful army has staged or attempted 18 coups in the past 80 years - including the ousting of Yingluck's brother, Thaksin Shinawatra, in 2006.
