Because of many things that have evolved, this can be construed as terroristic threats and becomes Federal which is a felony.
Do not let the Local COPS tell you they cannot do anything!
"You"
tell them you want a Police Report made out and you want the complaint # and a copy of the report. If they are in a place where they cannot make a copy, they must give you the Complaint #. It may cost you some $ but you have it in your hands for further investigation.
if you have a recorder and anything is said, keep a copy of it.
It doesnt have to be just a He She, it can be any combo of things.
RUGreek is right, if your local phone company does not keep a record after you have requested it, they are in violation of Federal Law. You tell the local Tele person I want a Supervisor right now. Point it out to them, they are required to do it I beleive up to three days.
