Private investigators work in a variety of settings depending on their specialty and on the case they are investigating. In general, they spend part of the time in offices, using computers and phones to conduct their research. They also spend time in the field, interviewing people in person and conducting surveillance to gather information on their activities and behaviors. Private investigators usually work alone but may work others if the assignment is complicated or they need help in the field. Their job is to gather information about crimes but not to enforce laws. Their work may cause confrontations and in some cases may turn violent; carrying a weapon may be necessary for these instances but private investigators don't always need to be armed. Private investigators work all hours of the day and night, holidays and weekends.
