 Law enforcement officers often receive inquiries and demands about their investigations that stem from unrealistic portrayals on television. In a 2010 survey of Canadian police officers, some were frustrated by these CSI-affected queries, though most saw them as opportunities to inform the public about real police work. New technologies and the increased public awareness of forensic science have stimulated new interest in solving cold cases and encouraged higher accountability among police investigators. However, the increased demand for forensic evidence can cause an unmanageable workload for forensic laboratories. Some crime labs process several thousand cases every year. Many law enforcement agencies have insufficient storage space for the increasing amount of physical evidence they collect. In some investigations, DNA evidence is not collected simply because there is not enough space to store it properly.
