In response to the recommendations of the coroner's inquest jury, former chief Bill Blair recommended that all plainclothes police officers be issued arm bands and raid jackets bearing the word "police" in an effort to increase their visibility in critical situations. Unmarked cars, which were already equipped with a plug-in police light, were to be supplied with additional emergency equipment, including a siren package. The proposals were phased in over three years beginning in 2008. Undercover officers also must wear, carry or have access to standard police use-of-force options such as pepper spray and batons.""
