My Mobile Witness is intended to be used as a precaution or deterrent. Take a picture of anything — a person, a place or something of concern you want to document. Use your best judgment when deciding whether to take a picture, video or text in secret or to announce your intentions. My Mobile Witness is NOT a substitute for 911. In the continuum that goes from doing nothing to calling 911, using My Mobile Witness falls somewhere in between, but if you are in doubt of what to do, call 911.
