What is the first step to take after a shooting incident when holstering?

The first step to take after a shooting incident when holstering is to make a decision to ensure scene safety. This is crucial because ensuring the safety of the scene involves determining if there are any ongoing threats or if the environment is secure before taking further action. Immediately addressing scene safety allows officers to protect themselves and others, as well as to maintain control of the situation.

Once the immediate safety of the scene is established, other actions such as assessing the weapon's condition, checking for injuries, and calling for backup can be efficiently addressed. However, if the scene is not secure, these actions could put the officer and others in jeopardy. Therefore, prioritizing scene safety aligns with best practices in law enforcement, as it helps in preventing potential further violence or complications post-incident.
