  • Why hire a Private Investigator when you can rely on Artificial Intelligence?

    Amidst the dazzle of technology, we cannot overlook the enduring value of human investigation. Human investigators possess a unique blend of intuition, empathy, and critical thinking that simply cannot be replicated. While Artificial Intelligence can sift through vast amounts of data and detect patterns, AI lacks the innate human capacity … Continue reading

FAQs

Surveillance Misconceptions

The amount of evidence required to prevail in court is often the biggest surprise to clients. 

In some cases, this can be even more true than others. In child custody cases, for example, it’s not enough to catch your ex-wife or husband in a single act of bad parenting. Rather, you need to establish a pattern of behaviors to convince the Court.

Painting this kind of picture can require much more surveillance than most people think. In fact, surveillance is largely a waiting game and it can take several attempts just to make one successful observation.

What is your role as a client?

Your role is to share as much information as possible with your investigative team. The more information you can share, the better. It makes the investigation more efficient and saves you money. 

Additionally, you should be as proactive as possible, although always in consultation with your investigative team, and your attorney if you have one. Certain types of information will be more readily accessible to you than it will be even to the most seasoned, professional private investigator. Family medical and financial records, for example, may be easier and faster for you to obtain than for a third party like a PI. 

We’ll discuss these issues in detail during your free consultation and help you come up with a list of ways that you can help in your investigation.

Can you find my long-lost friend or family member?

Probably, yes. 

However, the more pertinent question here, for many clients, is: what can we do with the information? 

If we are working with an attorney in preparation for litigation, then we can disclose certain information to the attorney in order to facilitate litigation. However, in private cases that are not connected to litigation privacy laws and ethical guidelines prevent us from finding a person and telling you their location. It may come as a surprise from a private investigative agency, but avoiding the invasion of other people’s privacy is a big concern for us, and we are proud to be a highly ethical agency. 

Nevertheless, we are always happy to find a person and then initiate contact on your behalf. In other words, with your permission, we can give someone the means to contact you.  

More often than not, acting as an intermediary and facilitating contact results in a successful connection between the client and the subject of the investigation.
