Kenya-RE Managers still walking free

Its sad to see that nothing has been done to Kenya-RE managers even after their scandal was exposed to the government. Sources say that the MD Mr Githaka and Amos Kimunya who happens to be the minister in charge of finance ministry happen to be good friends and their friendship extend to the state house no wonder he has all the protection and has not been charged yet.
Why does government spend so much time investigating something that has been paper trailed by the newspaper and if they have to get the information right....why not use the leads that have been provided. To my understanding some of the employees who came to know of this and passed on the information to others right now their jobs are in jeopardy. If the government is serious about fighting corruption then it should ease on employees at Kenya-RE and support them for giving out information rather than trying to seek who talked to the media.
