Clearly, the robber knew the casino intimately. Only a limited number of employees would know where the chips are stored and even fewer would have access. This guy either had inside information or is a disgruntled current or ex-employee.
His actions, in deliberately burning the gambling tables and jackpot machines, seem to indicate more than mere robbery. There seems to be some vengeance involved in wanting to destroy the casino's money-making assets.
His action seems to have a more suicide attack angle than pure robbery intentions. And by attack I mean attacking the casino itself, not so much murdering bystanders.
