What type of items are included in pocket trash?

Pocket trash refers to small, seemingly insignificant items that an individual carries with them, which can provide valuable insight during investigations or assessments. The correct answer highlights that business cards and receipts are typical examples of pocket trash.

Business cards can indicate relationships or connections with other individuals and organizations, potentially providing leads or context about a person's network. Receipts, on the other hand, can reveal recent purchases, locations visited, and consumer habits, which can be crucial for understanding an individual's behavior or activities.

The other options don’t fit this definition as effectively as business cards and receipts. Fictional documents may not be tangible, and internal reports are not typically items one carries around in a pocket. Confidential government papers, while potentially significant, are not considered pocket trash due to their formal nature and content sensitivity. Thus, business cards and receipts are more accurately aligned with the characteristics of pocket trash in investigative contexts.
