There is a difference between the information required to begin an investigation versus a limited preliminary inquiry. If law enforcement does not have information that establishes a reasonable suspicion of criminal charges, they are only authorized to begin a brief limited inquiry. If investigating agents reach the level for beginning a full scale investigation of criminal charges, they are authorized to use any lawful investigative technique with the least intrusive means to obtain the information. When deciding the level of intrusiveness, a judge can consider adverse consequences to an individual’s privacy and avoidable damage to an individual’s reputation. There are also a variety of ethical rules which must be considered. Criminal defense lawyer Stefanie C. Moon will examine all of the ways to challenge a criminal charge on your behalf.
