A randomized controlled trial of the impact of body-worn camera activation on the outcomes of individual incidents

What evidence supports the use of Body Worn Cameras in mental health inpatient wards? A systematic review and narrative synthesis of the effects of Body Worn Cameras in public sector services

“…However, BWCs were not found to impact response time or time spent on scene once contact was initiated (Wallace et al 2018). Research also shows a mix of statistically significant increases (Braga et al 2018;Huff et al 2020, Morrow et al 2016) and decreases (Headley et al 2017;Young & Ready 2016) in arrest rates, and one study reported no change at all (Wallace et al 2018). No conclusions can be drawn about the impact of BWCs on officer-initiated contact or arrest rates based on this literature.…”

“… 2018 ; Young & Ready 2016 ), and a third reported a decrease (Huff et al . 2020 ). Although (Young & Ready 2016 ) reported an increase in officer‐initiated contact, they also reported that officers were less likely to perform stop and frisks while wearing BWCs.…”

“…However, (Huff et al. 2020 ) reported a small but significant increase in use of force following BWC activation. There appears to be a trend toward decreased use of force after implementing BWCs, but inconsistencies in methods and measures across the literature make it difficult to draw solid conclusions.…”

“…The data used in this study were collected as part of an evaluation of body-worn cameras conducted in six of the seven Phoenix Police Department precincts (see Huff et al, (2020) for a full description of that evaluation). For the purposes of this study, which is not to evaluate the impact of body-worn cameras, I only examine incidents that occurred in the eighteen months prior to body-worn camera deployment (11/24/15 -5/23/17).…”
