Is it permitted to listen via scanner (two way radio) to local hatzolah, shomrim , fire dept. etc.
Is it considered geneivas daas ?
Answer:
This is not considered geneivas daas (see our article here for the parameters of this prohibition).
However, because these conversations are strictly confidential, and listening to them is a breach of confidentiality, it is not permitted to do so.
See, for instance, the discussion on phone tapping in Rav Shlomo Dichovsky, “Ha’azanat Seter”, Torah Shebe’al Peh 35, p. 57.
Best wishes.
