Federal Agent Owens Had Conducted a 2-Year Investigation of a Store

Federal Agent Owens had conducted a 2-year investigation of a store run by Paul that was believed to be involved in money laundering for an organized crime operation. Agent Owens obtained a court order for Paul's phone records and discovered that he frequently called Ron's cell phone. Ron's personal bank records showed that Paul's store transferred $100,000 to his account by wire on the first of each month. Agent Owens has filed an application for a Wiretap Act warrant to monitor Paul's store phone. The application for the warrant should be:

A) granted because organized crime is involved.
B) granted because of the length of the investigation.
C) denied because there is no showing that other investigative techniques will not work.
D) denied because there is currently no danger to life.
