> citizenry has to deal with on a daily basis

Sounds like a hyperbolic statement. Most citizens may be more likely to say that they do not have to deal with people who commit crime and lie to them on a daily basis unless you are in a very rough neighbourhood with very little law enforcement.

People who are policing do have to deal with this daily, however there is a change that the police could potentially form some kind of a sampling bias on new encounters with average looking citizens after dealing with so many lying criminals on a daily basis.
