Special investigators according to the Texas Code of Criminal Procedure are:

Special investigators according to the Texas Code of Criminal Procedure are classified as individuals who do not have the full authority of peace officers but still possess certain powers, especially relating to arresting individuals in felony cases. This classification allows them to operate with a specific focus while not carrying all the responsibilities and privileges that regular peace officers do.

This option highlights the unique role of special investigators, allowing them to perform necessary functions within law enforcement frameworks, particularly when investigating serious offenses. Their ability to make arrests in felony cases indicates that they still play a significant part in maintaining law and order, while their designation as not being full peace officers clarifies that their authority may be limited or specialized compared to regular officers.

In contrast, the other options do not accurately depict the status and capabilities of special investigators. While some may assume they could be classified as full peace officers, the distinction in their designation emphasizes their specialized role. The limitations on their activities regarding surveillance and community policing further clarify that their primary focus is more on investigating and less on broad community engagement or extensive operational responsibilities typically designated to peace officers.
