IMO, with the info you gave them, you should have given them enough
information to start looking for him. Ideally, you could have stuck with
the other car untill the cops got him, but you can't do all their work
for them. That assumes, of course, that the cops wanted to be bothered
with him to begin with and the dispatcher wasn't just taking the info
from you to humor you.
