Maybe it was the area I grew up in, but all 3 of our high schools had a policeman that worked solely on campus. We also had regular practiced "lockdowns" where we treated the school as if there was a gunman and focused on protecting the students. We never had any incidents, and I'd like to think it due to that preparation and proactive response. We didn't wait for something to happen before acknowledging it. I believe Target should operate similarly. We shouldn't wait for a string of armed robberies to consider how to most effectively prevent them.
What is the relative danger going to work in a Target store?
I decided to try to look it up. It's difficult because of course Target doesn't want people to know this data. I managed to find a
report that focused on Walmart that included data they had obtained from police departments that they used to compare the two retailers. Unsurprisingly, Target was considerably more safe and had less incidents. The 30 Targets closest to the high-risk Walmarts averaged 2 calls to the police per year for violent and serious offenses(assault, robbery, attempted robbery, homicide, kidnapping, rape, and sex crimes) once you factor out the 34% of all calls were to report automotive theft. I wish I could find data straight from Spot about it and get a more holistic view of what Target stores are experiencing. However, I think that looking at areas that Walmart sees the majority of its crime in gives a good sample of where Target might also see that crime occurring.
I'll leave this quote from the study here without comment: "Police reported 8 incidents involving weapons law violations at the 30 Target stores".
