How to prosecute anybody
Look around for "suspicious" behavior, i.e., behavior on the part of a private citizen that can be made to appear suspicious
Ruthlessly probe every element of the "suspect's" life, using the effectively infinite resources of the State, until enough "suspicious" behavior has been amassed
Assemble a huge list of charges to place before a grand jury
Present the case in such a fashion as to promote the less plausible accusations and obscure the more plausible ones, thus securing a grab-bag indictment
Offer the indicted person a plea bargain that will spare him centuries in prison and complete pauperization at the bargain price of a few years and/or a few thousand dollars.
