Shopping malls = sites of many people, social activities & crimes.
Demand for police is especially high at malls during the holiday shopping season (HSS).
In new article, we parked police cars at malls during the HSS to assess their effects on calls & visibility: doi.org/10.1016/j.jc...

My results revealed greater detection accuracy when the police vehicle was marked versus unmarked, with increases in accuracy as visual salience increased.
Under low visibility conditions, my results also revealed greater detection accuracy of marked vehicles when they had a B&W color scheme.

🚨 Police visibility = important metric for many policing activities.
It’s often assumed that physical presence of police equates to public sightings of police.
But do ppl always see police when they're present?
In my new JOEX article, I find the answer is *no*: doi.org/10.1007/s112....
