There are many legal/factual problems with this episode:
- putting up flyers on shop doors is protected by the First Amendment. It is not littering. There is no reason for police to be involved.
- a sextalk phone operation is legal, as long as customers attest they are over the age of consent. The government has no business regulating what happens in a citizen's phone calls, and if a crime is suspected then a warrant can be obtained.
- the telecom operator does nothing to protect her business nor her customers. She agrees to hand over telephone records without a warrant and in exchange for a date with an officer.
