There's a mindset out there by some, that's roughly "it doesn't matter what the process is, this is so important that we need to break the rules to fix it." In my opinion, no, we don't. I'm remembering, maybe mis-remembering a case where the constitutionality of DUI check road blocks was questioned. The reasoning being, that there was by definition no probable cause for the stops, they were checking everyone. The court ruled - if my memory was right - that while it wasn't constitutional it would be allowed, because drunk driving is so serious that we need to ignore that rule. Well, again my opinion, that's the wrong answer.
We collectively need to wrap our heads around the concept that some problems, even bad ones, can't be completely solved. Anyone doing risk management and flying airplanes should understand that. There's no such thing as 100% safe, there's never the perfect day, perfect airplane, perfect pilot. We manage the risks and we balance the desired goals with them. That's a core concept in flying. Here, with all of this, we should be recognizing that there's no penalty in some areas for ignoring probable cause and punishing completely innocent people. That's not acceptable. We can't - repeat cannot - change the fact that there will always be some percentage of people on the road driving drunk. We can change the environment so that sober people aren't driving in fear of law enforcement.
And no, I've never had a problem with a traffic stop myself, that's not may angle. And yes, I've lost a family member to criminals, I do understand that type of frustration. But you can't sweep the good up with the bad in trying to eliminate the bad. I'm fine with burying the bad, in a literal sense, but only if we're as close to 100% certainty as we can be. I kinda think we should have a drinking license just as we have a driver's license, in part because drunks don't need cars to hurt people.
And back to the FAA part of this, if we're going to continue down the road where in some states there's no probable cause effectively required for an arrest, then it would make sense to remove any conditions triggered on an arrest from the FAR's. That arrests just become a thing that they assume anyone who drives a car may have.
