Yes. Let's add in that all of these young people are at that age where one considers themselves invincible. They hear a bump in the night...and they turn their airpods up. I hear one (53), and I can be almost certain that someone is in my home ready to rob and kill me. Young people have a different mindset. I'm envious of that at times. I was blissfully unaware during my college days, as I think most people are.
Additionally, to my knowledge, there was no reference of any major crime activity occurring in the area. There was no reason for she, or anyone else, to be overly cautious.
Put yourself inside your own head at 20 (ish) during a football/homecoming weekend at your school or university. You see a dude in passing in your hallway. You likely wouldn't assume he's a murderer, but instead a friend of one of your roomies.
There were 3 murders on my university campus during my freshman year. Did this change my sense of invincibility? Nope, because I was brought up with the strict doctrine that God would look after me. I'm quite serious. I had a divine co-pilot. As I learned more about crime that year (having taken a job as a crime scene photographer - briefly), my views slowly started to shift. Then, I was the victim of a significant theft (it was devastating! how could that happen!)
Still, I didn't change my habit of going out for late night solo walks and runs. A murder in my second year of university, near midnight, near a place that I frequented, did make SOME difference. But I persisted in my naiveté longer. Heck, on my first DAY of freshman year, I got in a car with a stranger - because he was a student! (A grad student!) When he turned away from the direction I asked him to go, I jumped out at a stop sign (thank goodness for the way roads had many stop signs on my campus). That changed my view about stranger rides.
The murder of yet another person in my junior year (off campus, but some place I frequently went) was the clencher in my progress toward safety as that same person had warned me that it was not a safe part of time and given me quite the parent-style lecture (she was a woman of about 50).
But still I kind of laughed at another grad student for going and getting a permit to carry mace, but after some reflection, decided to do so myself, probably due that one time that someone pulled a knife on someone else at a concert - it was the Allman Bros - and I was standing in between them as it went down, not knowing either of them; I will say that I first froze, then fled, abandoning the entire idea of getting something at the snack bar.
I went and found my pepper spray again, because of this case. I will do better with my students on these topics, this semester (and will be using this case in a couple of classes, so I do hope parents realize that their students are going to be "triggered" if they study psychology, criminology, anthropology, sociology, forensics or a number of other subjects, especially right after a crime like this one. Cultures vary by the kinds of crimes they have, that's for sure.
Moscow, ID has had murders (3 multiple homicides before this one, IIRC), suicides, at least one murder-suicide, and a death still under investigation, while WSU had a student take other students hostage (with a gun) in December. I hope these are used as an opportunity to help students actually BE safer, not just feel safer.
