Whether the INS's factory surveys seized the entire workforce under the Fourth Amendment because agents positioned themselves near the exits while the surveys were underway.
Holding
No. The surveys did not seize the workforce as a whole.
Reasoning
A Fourth Amendment seizure occurs when an officer uses physical force or a show of authority to restrain liberty such that, in light of all the circumstances, a reasonable person would believe that he or she was not free to leave. But not every interaction between law enforcement and the public is a seizure; the Amendment is concerned with arbitrary or oppressive interference with personal security and privacy.
The workers' ordinary freedom of movement was already limited substantially by their voluntary obligations to their employers. At the time the surveys began, employees were performing their normal assignments, and the record showed that INS agents did not prevent them from moving about inside the factories. Disruption alone did not transform the operation into a detention of everyone present.
The agents' placement near exits did not establish that the INS was preventing employees from leaving. The record did not show that agents generally blocked departures. Their evident purpose was to ensure that persons in the factory could be questioned, and the possibility of being asked brief questions at an exit did not reasonably imply that lawful workers would be detained.
The agents' conduct consisted of questioning employees and arresting persons for whom they developed probable cause to believe were unlawfully present. Workers who answered truthfully, or who simply declined to answer, had no objective reason to think they would be detained. Indeed, two respondents left the building during a survey without restraint or questioning at the exit.
