Try reading my comment again, you fucking dumbass. EVERY DETECTION METHOD HAS A FALSE POSITIVE RATE, AND THE FBI'S FOR COUNTERTERRORISM APPEARS TO BE ABOUT 0.5 PER YEAR.

It could not "literally happen to any of us with a little bad luck". You are several orders of magnitude more likely to be struck by lightning. More people have won $100,000,000 in a lottery than have been held in non-criminal custody by the FBI due to investigation mistakes.

That's an error rate so low it would make jetliner engineers faint with envy. (You are orders of magnitude more likely to be killed by such an engineer than inconvenienced for a few days by the FBI.)
