For any prospective clients with a case in New York, please understand that New York City has concerns, like several other large cities, offers some special considerations surrounding spousal surveillance. Because people in New York get around using many different modes of transportation, traveling through intense traffic flows, we often recommend more than one investigator to get the job done correctly. This is not an attempt to simply charge more. Two investigators can stay with someone longer and more discreetly than one in any environment. In New York at rush hour, it is almost always necessary to keep a tail in place in that environment. Not using two or more investigators greatly increases the odds of losing someone or being detected.
