# Supporting Law Enforcement and Forensics Despite the myth of invisibility, **Bitcoin has helped authorities trace and prosecute a wide range of criminal cases**. One of the most powerful examples was the global takedown of “Welcome to Video,” a dark web child exploitation site. Investigators used blockchain analysis to follow Bitcoin payments from users to the site’s operators. Once law enforcement identified an address and tied it to real-world identities via exchanges, the entire history of that address became accessible. The outcome was more than 300 arrests in over 30 countries. Bitcoin’s transparency made this possible. Other cases have involved ransomware payments, fraud schemes, and dark market sales. Investigators do not need special access; **they need only the blockchain, analytics tools, and off-chain data (such as exchange records) to connect identities to transactions.** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
