If there is a possibility of any evidence being preserved at a business robbery, what is the best practice to ensure evidence will be preserved?

The best practice to ensure evidence is preserved in the event of a business robbery is to secure video footage. This is crucial as video surveillance can provide valuable information about the crime, such as the suspect's appearance, their mode of entry and exit, the time of the incident, and the actions taken during the robbery.

Securing video footage promptly helps prevent data from being overwritten, which can happen if recording systems operate on a loop. This evidence could be essential in identifying suspects or corroborating witness accounts. While locking doors, notifying authorities, and searching for witnesses are all important steps following a robbery, they do not directly address the immediate preservation of potentially critical evidence, such as video recordings. Thus, focusing on securing video footage maximizes the chances of collecting vital evidence that could lead to solving the case.
