Summary: This short practical will cover the basic steps required to create a simple NetLogo model. The application area is not related to crime, but it will nevertheless demonstrate how the software works and allow you to become familiar with a simple agent-based model.
The instructions can be downloaded from here.
To learn more about NetLogo itself, you can follow this link for the lecture and introductory pages.
The advanced model (mentioned at the end of the practical) is also available to download (don't do this until after the practical!).
