Respect for law

"The Congress of South African Trade Unions and the South African Communist Party are planning a 'million signature campaign' to convince President Thabo Mbeki to drop corruption charges against his former deputy, Jacob Zuma." - IOL

Would COSATU also support a hypothetical former convicts of South Africa "million signature campaign" to force Thabo Mbeki to drop all murder charges against those in prison? The process and rule of law is robust; once commenced, it cannot be wished away on the whim of a party. On the other hand, could this be the first signs of COSATU realising that he may be found guilty in a court of law?
