Dina is walking around the store with Bo, sharing some of the resources Cloud 9 has invested in to deter crime. Only half of he cameras are actually function, and the security guard isn’t holding an actual weapon, but potential criminals don’t know that. The goal is to give the illusion that a criminal would be caught.
Dina and Glenn accidentally ruined some ballots by spilling a pot of coffee. They are worried they will be accused of tampering with ballots and face jail time. If they both stay quiet, then nothing will likely happen to either of them. There’s an incentive to confess and try to get the other in trouble, but they both know who would responsible. Since they do not trust each other, they try to set each other up by pretending to be each other and recording their voices. This serves as a credible threat in the case that one of them rats the other out.
As Dina and Amy go searching for Bo, Amy notices that Dina doesn’t have a radio in her truck. It turns out that Dina special-ordered her truck without a radio (even though it costs more) because she believes it would make her truck less appealing to potential thieves. If criminals behave rationally (which Gary Becker argued that most do), a truck without a radio wouldn’t be worth the potential cost associated with car theft. Dina has removed the incentive to steal her truck.
