One specific use of alibi sousveillance is the growing trend of police officers wearing body cameras while on patrol. Well-publicized events involving police-citizen altercations (such as the case of Michael Brown in Ferguson, Missouri) have increased calls for police to wear body-cameras and so capture evidence of the incidents, for the benefit of them personally plus the criminal justice system as a whole. By having officers use sousveillance, police forces can generate hours of video evidence to be used in cases like that of Michael Brown, and the video evidence can act as an important alibi in the judicial proceedings in regards to who is truly at fault. Regardless of the outcome of such events, contemporaneous audio-video evidence can be extremely valuable in respect of compliance- and enforcement-related events.
