calls to arrest former government officials poltical drama?

almost in all of the gatherings of the ruling MDP some of it parliament members and most of the time its parliamentary leader calls on the government to arrest former government officials over corruption and charges on to overthrow the government. till today the calls are not acted on. this raises the question every time MDP top officials call on the government to arrest former government officials are they playing a game to render support to them. a presidential commission have been in place and a lot of cases are said to be investigated by them till to date no case have been finished or sent to the courts. there is no news of any action taken from the commission. wonder of they are doing their job or is this also another game by the government. are they afraid if they do start taking action then their former vice president may also have to be investigated . hmm
