It could be any number of reasons, typically it would be related to the investigation of a crime or a potential crime. They could be looking for a particular person whom they believe may be in contact with the person or place under surveillance. They could be keeping watch on a person they believe might commit a crime or on a location where a crime might be committed. Surveillance in and of itself does not mean that a crime has been or will be committed by any of the persons under surveillance or their associates, or at a particular location.

A signed retainer agreement is required before an attorney /client relationship is established. The analysis provided is meant solely to provide general guidance about the legal issue presented.
They are looking for evidence of a crime. They may be trying to gather sufficient facts to obtain a search warrant or hoping to witness something that allows them to search without one. Police would not be expending resources on an investigation unless they believed they had credible information that an offense was being committed.
If you are the subject of a police investigation, it would be wise to start consulting defense attorneys sooner than later.
