It is a common misconception of the people who a private investigator has any type of police powers. It is actually illegal for private investigators to wear any sort of uniform and carry badges in different countries and they are also not allowed to carry any kind of hand gun or ammo. They also don’t have any right to enter a private property without the permission of the owner and can’t access the email records, bank records or phone records of anyone without their permission.
Private investigators do not have any distinct rights beyond the rights of an ordinary citizen and they cannot make an arrest even if they have substantial evidence against the person they are investigating.Although different countries have different laws but the laws of United States clearly state that private investigators are not law enforcement officers and cannot be granted any kind of police powers like making arrest or the use of force etc.They are usually hired by law firms, privates businesses and individuals to get the information they need for making the right and informed decisions. These investigators simply help their clients in finding the fact by collecting the necessary evidence and identifying the risks relating to a problem that their client is most concerned about.
In order to get the job done private investigators rely on a variety of resources including public records, close observation, court records, government archives and even human intelligence regarding the person of interest in any given case.
