I think it is random. But today on Diamond heist, I only had 3 bulldozers (after we disabled all the boxes without anyone noticing). We completed the game in 10 min with hardly any resistance.
The second round we got discoverd within seconds and when we finally had the vault codes there were tazers everywhere + lots of swat. I think the more careful you play the less police you get (+ofcourse camera's) if the system is not random.
Fallout 3, Borderlands, Resident Evil 5, BurnOut, LittleBigPlanet
