There is no equivalence between a meter reader and a police officer's situation. Some subset of police interactions may be similar but many will be very different. A police officer's interaction is much more likely to be heated, urgent, close quarters, and unavoidable. A meter reader can just leave if necessary, which is what they do.

For example, police officers frequently have to enter a home during a domestic dispute with a dog that is riled up due to its owners having a physical altercation.
