We discuss the results from our researcher-practitioner collaboration with respect to policing research & practice.

We are especially excited about this project because it included participation from 3 PDs in 3 provinces of Canada.

Our analyses revealed little effect of the presence of police cars on calls at malls, with possible effects observed at only one mall.

However, our analyses revealed effects for police visibility: with variation in reported sightings of police cars by mall patrons across the study period.

As part of study, we parked police cars (of different designs as randomly assigned) daily outside of malls at conspicuous locations in 3 Canadian cities.

We then compared the number of calls along with public sightings of police cars at malls during intervention period to weeks before/after.

We discuss our findings in the context of policing research and practice, including as it relates to social media and community policing.

I am very proud of Janine for this work and excited to celebrate her first publication. 👏

From the beat to the tweet: the use of Twitter (X) by police officers

Consistent with organizational-level findings, we found that officers frequently employed the push strategy when tweeting.

Nonetheless, some variation in engagement style and posting practices emerged by officer characteristics, including officer gender, officer rank, and frequency of posting.

We created a dataset of officers who use Twitter (X) in a professional capacity and then analyzed their characteristics and tweets.

This resulted in a sample of 66 officers and thousands of tweets.

We coded all tweets for content using a detailed codebook.

I discuss what my results might mean for how police agencies design and deploy their police vehicles.

I also highlight the implications of police vehicle designs for research regarding police interventions.

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.

I strategically manipulated the design of the police vehicle in the images: sometimes it was marked (either with a B&W or all-white color scheme) whereas other times it was unmarked.

I also varied how visually salient the police vehicle was in the image: ranging from low to high.

As part of my experiment, I tested if police vehicle designs impact public detection of police vehicle presence.

I presented randomly assigned images to participants under the guise of a visual detection study and asked them to indicate if/where a police vehicle was located.
