What about ill-gotten wealth of erstwhile AL govt.?

During the previous tenure of the AL government many ministers and MPs amassed huge wealth. I believe this wealth belongs to the nation and should be confiscated by the government and used for the development of Bangladesh. I am surprised that no 'show cause notice' has been issued against any of them and they even claimed this to be “normal”. I also believe this would be an opportunity for AL to regain their reputation.
