Understanding Your Local Problem

The information provided above is only a generalized description of convenience store robbery. You must combine the basic facts with a more specific understanding of your local problem. Analyzing the local problem carefully will help you design a more effective response strategy.

Your analysis should examine the different risks evident in the stores, and be particularly focused on repeat victimization. Gathering information is labor-intensive and detailed. The more standardized your department's information-gathering process, the more opportunity you have to understand your robbery problem and reach conclusions.


In addition to criminal justice agencies, the following groups have an interest in the convenience-store robbery problem and should be considered for the contribution they might make to gathering information about the problem and responding to it:

  • Local business associations (e.g., chambers of commerce)
  • Convenience store associations
  • State and federal workplace safety agencies
  • Worker's compensation agencies
  • Insurance companies
  • Convenience store corporation loss-prevention departments
  • Private security firms.

Asking the Right Questions

The following are some critical questions you should ask in analyzing your particular problem of convenience store robbery, even if the answers are not always readily available. Your answers to these and other questions will help you choose the most appropriate set of responses later on.

Since environmental details are particularly relevant to this type of crime, it is important to listen carefully to victims' description of the robbery. You can collect pertinent information by asking victims incisive questions about the setting and circumstances of the crime.

It is also crucial to interview as many apprehended offenders as possible. to find out how they make their decisions. See Problem-Solving Tools Guide No. 3, Using Offender Interviews to Inform Police Problem-Solving, for further guidance on gathering information from offenders.

Current Responses

  • What is the clearance rate for convenience store robberies?
  • What security measures have the stores taken to prevent robbery?
  • Do store employees follow correct cash-handling and other robbery prevention procedures?

Measuring Your Effectiveness

Measurement allows you to determine to what degree your efforts have succeeded, and suggests how you might modify your responses if they are not producing the intended results. You should take measures of your problem before you implement responses, to determine how serious the problem is, and after you implement them, to determine whether they have been effective. All measures should be taken in both the target area and the surrounding area. For more detailed guidance on measuring effectiveness, see the Problem-Solving Tools Guide, Assessing Responses to Problems.

The following outcome measures can be useful in assessing whether your responses have impacted the convenience store robbery problem:

  • Fewer reported convenience store robberies and related calls for service
  • Fewer repeat victims and offenders
  • Fewer robbery-related financial losses and insurance claims
  • Fewer business closures resulting from robberies
  • Fewer or less-severe injuries of employees and customers resulting from robberies
  • Greater perception of safety among store owners, employees, customers, and the community at large.

In addition, the following process measures might provide some indication of the degree to which selected responses are being properly implemented:

  • Higher proportion of stores following standard security practices, installing security devices, and/or using guard services
  • Higher proportion of store personnel formally trained in crime prevention.
