Giqcass, great point that few ever consider. There will be perspectives all over the place.
We live near a college and subscribe to their alerts, which include the ability to receive a call. We also happen to have a student on campus. Most recently the system alerted us to a potential shooter on campus. We immediately texted our son to ensure he was not near the area.
Within minutes, it called back with an all clear. Some ROTC students were returning non-functional weapons used in drills and someone saw them and acted (properly) to report it.
Public safety officials should be pushing systems like this and using them IMHO. First world problems getting a handful of alerts for public safety a year.
As a former firefighter, I can tell you that the foam is designed to surpress fire by cutting off the air supply as quickly as possible. Whether it's a mild irritant to skin or not is really irrelevant as it's only used in potential dangerous situations where water can't be used or isn't as good given the problem at hand.
