The senate hearing like i said will be a waste of time, PCSO will just show them the copy of all winning tickets, or those 433 will testified, and last sort is showing the machine or software used for generating random number result.
If there is cheating happened the questions are, why just now?
If not, so all the jackpot winners in the past were all fixed? If those were all fixed we should see a pattern of winners, like most of them have family related to PCSO, government, etc. but its not. I'll say it again, this is just pure coincidence.
