A-bian supporter's sign

阿扁加油、阿扁無罪
侵犯人權、自由
司法不公、不義倒退
民主、治法擔憂
台灣人覺醒吧！

Rough translation:

Go A-bian! A-bian's not guilty.
Infringement on human rights and freedom.
The judiciary is unfair and unjust. Concern about democracy and rule of law going backwards. Taiwanese people wake up!

About one hundred supporters of former President Chen Shui-bian gathered outside the Taipei Detention Centre on Sunday.
