Scholarly articles are the heart of much literature research in criminal justice. The basic pattern in APA Style for citing these articles is:
Author, A. A., Author, B. B., Author, C. C, & Author, D. D. (2012). Title of the article: Subtitle if included on original. Title of Journal, xx, ###-###. doi:xx.xxxxxxx
If a doi is not included, provide the name of the database, or the journal url. Examples of these 2 situations are:
Bloss, W. P. (2009). Transforming US police surveillance in a new privacy paradigm. Police Practice & Research, 10(3), 225-238. doi:10.1080/15614260802381083
