Which of the following concepts includes property checks and high visibility patrols?

The concept that includes property checks and high visibility patrols is preventative patrol. This approach focuses on deterring potential criminal activity before it occurs by making police presence known in the community. High visibility patrols serve to reassure the public and can act as a deterrent to crimes such as vandalism and theft. Additionally, regular property checks help ensure safety and security, further contributing to the prevention of crime.

In contrast, reactive patrol emphasizes responding to incidents that have already occurred rather than proactively preventing them. Investigative patrol typically involves the investigation of crimes after they've been reported. Discretionary patrol allows officers to decide how to allocate their time and resources based on their judgment, which may or may not include property checks or high visibility efforts. Thus, preventative patrol is specifically designed to engage in strategies that help reduce the likelihood of crime.
