Question: <https://www.cnn.com/2018/05/09/us/yale-student-napping-black-trnd/index.html>

From what I've read, Connecticut is not a stop and identify state.

However, I understand that people are required to identify if police have a reasonable suspicion that a crime has been committed, is being committed, or is about to be committed (but if there is no such suspicion, they are not required to identify even in stop and identify states)

But does it qualify as reasonable suspicion that another student called police and said Siyonbola "appeared they weren’t … where they were supposed to be"?

And if so, what laws might be put into place to protect individuals from situations like this where someone makes a prejudiced police complaint against them?

Answer: 
Since the incident was on private property (inside a building), a person does not have the same right to be there that you would have on the street outside the building. Yale police therefore can legally make a determination whether a person is trespassing (for example, by asking for identification), especially when there is an allegation that a person is trespassing. A law holding a person criminally or civilly liable for reporting their "suspicions" to the government without e.g. "reasonable suspicion" could easily run afoul of the First Amendment.
Yale University is private property. The Yale Police Department and administrators can ask anyone at anytime to identify themselves.

The police responded to a complaint; they can't evaluate a complaint for "reasonable suspicion" or lack thereof until they investigate and talk to all involved parties. The officers investigated and then "...admonished the student who called police, saying Siyonbola had every right to be present..."

Yale spokeswoman Karen Peart told CNN, “We believe the Yale police who responded followed procedures.”

Again, Yale is private property.
