Buddhist monks join thousands of members of "red shirt" movement during their gathering at the Democracy Monument in Bangkok June 24, 2012. Thailand's "red shirts" turned out in force on Sunday to warn the judiciary they will not stand by if a plan to amend the constitution is rejected, a rewrite critics say is aimed at allowing exiled former premier Thaksin Shinawatra to come home. The red shirts chose June 24 for their latest gathering as it marks the anniversary of a revolution that brought an end to absolute monarchy in 1932.
