Your actions were in poor judgement, but are no less in violation of the Communications Act of 1934 than services such as the Incident Page Network and Mountain NewsNet. Both of these services have individuals, or "dispatchers", listen to scanners and then divulge and/or publish the information that they hear on the scanners via distribution lists that go to 3rd parties via pagers, e-mail, or other text forms of communications. To me, you're not violating any more laws than anyone else is who is participating in a sending or "dispatcher" capacity for the aforementioned services, or any other similar services.
