NEW: Sen. Josh Hawley sends a stark warning on the risk of Americans losing their privacy rights amid increased Flock camera use. "This is still the United States of America, and it shouldn't be that when you walk out your door in the morning, you just have to agree in assent and accept the fact that you're going to be on camera morning, noon and night.” “You'll be tracked by anybody and everybody in the world. You'll have no privacy whatsoever." "You'll be tracked when you take your kids to school and tracked when you go to church and tracked me to go to the grocery store." ▻
