Belated thanks for the link. I had thought after the Snowden video which showed how to disable the mic on a common cell phone, there might be some hope for project Ara. Alas not, it's been cancelled. https://en.m.wikipedia.org/wiki/Project_Ara. Russell Sent from mobile.

Interesting tech news about Stingray surveillance. I wonder if there is some way to detect that an intruder has captured your signal. You can test for capture and cause them to power down by having someone near you call 911. Apparently authorities have to let EMS calls access the real network. I think black hats.... umm not so much.
