Not FBI but my phone.....so if phones can do this I am sure FBI/govt agencies have more powerful tools......
I was in a hurry one morning to make the hour drive to where I was volunteering. I threw a breakfast bar down on the truck seat next to me & tossed my phone next to that. Not a word spoken about it cause I was driving totally alone. Later that day I was getting adds for that EXACT kind of breakfast bar. Coincidence?.....I don't believe in coincidences
