Dogs Cows match

Call me naive, call me stupid, but this looks like this is impossible to prove......

UNLESS Tandy put the bet through his account or unless the fellow people involved DIDNT transfer money into and out of Tandy's accounts and unless all parties DONT deny it, then HOW on earth are they going to prove it?

If i am a player and i get my best mate to place the bets, no transfer of funds between acc's etc, and we deny it, then i am sorry, this is impossible to prove......

Realitically, if i am a player and my best mate puts a $100k bet on Fg to be the first scoring play and i kick a Fg after 3 mins.......It will look dodgy as hell, but if there is no nexus between transferring accounts, we both deny it, then i am serious, how can they PROVE IT - EVIDENCE.

Think about it, this will have to be proven in the court of law........So what if there is video footage of someone placing bets.......its not Tandy......
