If police, FBI, or CIA were investigating the neighbor would it make it legal for them to use the technology to help spy on them? My example would be monitoring the targets home phone service so they can receive the incoming phone calls of the target home phone so that they can receive the phone numbers of the people who are calling the target house so they can spy on the people that call using their number as well. When the target phone makes a phone call, they can listen on whom they are having a conversation with real time and know what number they dial so that they can spy on the phone number they dial as well. If they use a mobile device such as an IPhone, or Android Phone, if they just have the number of the phone, they can track them, receive their outgoing and incoming phone calls, receive their texts messages outgoing or incoming. These software programs like Highster Mobile, Auto Forward Spy, ddi utilities that use to claim that you needed physical access to the phone you wanted to spy now say that you do not need the physical access of the phone you just need the login information. However, from many people that I have talk to they say all you need is the active working phone number of the target phone. Anyhow, is it legal? If I can prove my neighbors are doing this what can I do legally have them arrested.
