The researchers have examined data on felonious assaults of police officers and identified spatial and temporal correlates and risk factors. I like their format, where these findings are distilled into "implications for practice"--observations and recommendations set apart in gray boxes within the report. While much of this may be common sense for seasoned officers, it's still a valuable reminder.
I made a minor contribution to the content by providing some data and very rudimentary analysis to Dr. Caplan last fall, described in this post from October 16. Lincoln's data ends up as a case study on page 13 of the report. I'm very interested in research, and really enjoy the occasional opportunity to contribute to the body of knowledge in public safety.
Beware the wee hours, officers, and do not let your guard down at facilities where you may have a certain comfort level due to your familiarity with the surroundings, such as hospitals, detox centers, the jail, and--the police station.
