This article gives a little more background on the Janitor's involvement. He reported CV
three times to no avail. I wonder if Brown staff are instructed to contact the third party security contractors, since it seems like he tried awfully hard to flag the suspicious behavior.
Also of note:
So it sounds like LE probably had a good idea of who they were looking for (perhaps a sketch?) fairly early on.
I do really feel for Lisi - it seems like he had great instincts that something was wrong, went out of his way to notify someone.. and then no further action was taken. This quote really got me:
Lisi said that the person he saw (CV) was “visible” to him and yet not to the security. It makes a lot of sense.
The “algorithms” that we use to determine "in" or "out" depend on our oikos. (This Ancient Greek word used to mean “household” and today, it means “relational sphere” and “sphere of influence”.)
So for the janitor, the oikos at Brown is the physical building plus, the students and the professors. He saw someone who “didn’t belong to his oikos”. For the janitor, Valente was the “extra” factor.
Same with John. John was unhoused former Brown student. So his oikos was all Brown + people+ the area around it, and the man’s he saw fit neither. (He even looked into CV’s car).
What is the security man’s oikos?
He is probably looking for some kind of a terrorist, a menace. I don’t know what he’d look for professionally, but probably, the outline of a gun, maybe they scan purses. However, the fact that CV looks neither like a student nor like a teacher (or even a parent) escapes him. In the security’s world, If CV doesn’t have a gun on him (I suspect that he didn’t on that day), he fits in.
Possibly, for the security, CV who has the aura of a "mad scientist" can probably pass for one, but he deceived neither Derek nor John. In this context, it is interesting that John described CV’s clothes as being from Walmart (and it was not judgmental.) To guess what John thought: students from Brown dress on a budget, but they don’t shop for clothes in Walmart.
JMO: the security indeed didn’t see CV but it doesn’t mean that they are bad “security watchers”. They just made a wrong assumption. From their self-contained perspective, they were dismissive of the "insider" Lisi's information.
Two weeks later, all the security was asking the public to help. Sad, indeed.
So I feel for Lisi, too. Among other things, it shows that he is a great janitor for Brown who loves and knows the place.
