Recorded Crimes and Offences Involving Firearms, Scotland, 2020-21 and 2021-22

Statistics on crimes and offences recorded by the police in Scotland in which a firearm was alleged to have been involved or where a firearm was stolen.


Annex 2: Data collection process

Some statistical publications draw their information from databases that relate to the specific topic (for example the National Statistics on Recorded Crime, or Homicide). In the case of firearms offences, a topic-specific database is not available, and as such the data collection process has always relied on a mixture of automated and manual checks. The most effective data collection process is one that maximises the chance an offence which involves the use of a firearm is identified, and minimises the risk that one is accidentally missed out.

As outlined previously, each Police Scotland division provides an individual data return based on queries run on their individual Crime Management System (CMS) to identify crime records which included the use, or alleged use, of a firearm. These are reviewed and collated by Police Scotland’s Analysis & Performance Unit before being submitted to the Scottish Government. The methods available to analysts vary depending on their particular CMS and as such a combination of the following steps are typically used to identify any relevant crime records:

  • a search for all crimes where their description implies the use of a firearm (for example Reckless conduct with firearms)
  • a search for all crimes that include either a specific weapons-marker or a modifier that describes the weapon used - for example Air gun, Hand gun or Rifle; and
  • a key word search of all crimes to identify any potentially relevant cases that were not identified during the two steps above

Once these preliminary searches are complete, a manual interrogation of each crime record is conducted to confirm whether the record should be included and if so to complete the data return with the required information (i.e. offences committed with weapon, type of weapon, characteristics of those involved etc.).
