Nothing doing on the "regime change" issue. Even IK has moved on from this episode and all the military has to do is rely on the constitutional move around VoNC as the reason for ousting IK's government. They have to defend nothing else.
On the issue of financial records, mind you I am not calling it corruption just yet because all of the information we have is from government tax records and these records also include those of others in the extended Bajwa family. Keep in mind, If there is corruption, usually it is hidden as was disclosed in the Panama papers etc. So all that the government needs to do is trace back the funding reported in the tax returns to find out whether it came from the sale of government allotted real estate or some other streams.
As I have stated in another thread, no CoAS should be given multiple plots etc. This entire practice has to be curtailed with retiring general staff officers perhaps just getting a plot for their own residence to build on with their own money.
