Abstract: Apparatus and associated methods relate to a system including a portable hardware device having a radio antenna, the device being operably coupled to a network, where the device includes electronics for scanning ambient radio messages using the antenna, evaluating a message for sentiment (e.g., intent-to-harm) using at least one artificial intelligence technique, and upon determining the presence of intent-to-harm, transmitting an alert signal over the network to a target entity as determined by a set of alert transmission rules based at least in part on the content/context/metadata of the message. In an illustrative example, a portable pack may be preconfigured with automatic language translation and speech detection capabilities. The pack may scan ambient radio signals for specific words/phrases of interest (W/POI).
