The Columbia Police Department was asked to provide a recent six months' block of data regarding TASER usages to the Citizens Police Review Board. At the time of the request, the most recent six months' data spanned November 15, 2009 through May 15, 2010.

The data provided includes the following:

• The date
• The type of use
  • Did the officer simply display the laser light?
  • Did the officer just do an arc display?
  • Did the officer actually deploy the TASER? (TASER application or "TA")
• Were the TASER probes deployed?
• Was the usage a Drive Stun?
• Was there any injury as a result of the TASER usage?
  • Any time there is probe deployment, or a drive stun, medical personnel are always called, as a precaution
  • There were no injuries to any suspects caused by any of the TASER usages. The probes leave marks on the skin as noted in the data
• Was the TASER usage effective or not?
• What was the type of incident that required a TASER usage?
• A brief synopsis of the incident

The data show that in six month's time, officers actually deployed their TASER devices (probe deployment or drive stun) just twelve times, nine of which were effective.

Officers used the light display or arc-display to gain suspect compliance, without having to deploy the TASER device, fifteen times, with twelve of those times begin effective. In the other three instances, suspects became compliant but officers could not ascertain if that was solely due to the presence of the TASER device.
