Keep on chipping away. Eventually the dam will spring a leak and then break. 

My own view is to go for a few minions first, such as Chawla, Howa, vd Merwe and Essa who are demonstrably criminals. They will roll over, and then the toasters will be in full production.

Find the most obscure thread, pull and unravel the whole edifice, which is built on lie after lie.
