Does the police marking sender on every mail

In most countries, the police do not mark every piece of mail they receive. However, there are certain situations where they may mark or inspect mail:

  1. Suspicious or illegal content: If the police receive a piece of mail that appears to contain illegal or suspicious content, such as drugs, weapons, or child pornography, they may mark or inspect the mail to investigate further.
  2. Investigations: During an investigation, the police may mark or inspect mail as part of their evidence collection process. For example, if they're investigating a crime and suspect that a piece of mail may be relevant to the case, they may mark it as evidence.
  3. Counterfeit or fraudulent mail: The police may mark or inspect mail that appears to be counterfeit or fraudulent, such as fake checks or credit cards.
  4. Mail related to a specific crime: If the police are investigating a specific crime, such as a theft or burglary, they may mark or inspect mail that is related to the crime.

In general, the police do not mark every piece of mail they receive, as this would be an impractical and resource-intensive task. Instead, they focus on investigating specific cases and situations where mail may be relevant to the investigation.

It's worth noting that the police may also work with postal services and other law enforcement agencies to identify and intercept illegal or suspicious mail. In these cases, the police may not mark the mail themselves, but rather work with the postal service to intercept and investigate the mail.
