The sole purpose of RID was to be able to locate the pilot. To assume that RID is not now being actively used to locate drone pilots would be naive. You should now presume that every public event drawing large crowds of people where security is potentially at issue is tracking all surrounding drone activity broadcasting RID, as are all private security and LEO everywhere. This includes areas with and without TFR's and NFZ's. Amusement parks, sporting events, college campuses, golf courses, zoos, sporting events, companies with large private campus buildings, all private property, national parks, state parks, near fires, and anywhere near airports.
Again, it completely depends upon where you are flying, and the appearance of your flight activity to a concerned or paranoid person. Try flying around pot fields off the grid in the backcountry, even if you don't know where the pot fields are. They'll come find you using RID, too! It's a new tool for security, used for both good and bad.
Anyone zealous about their privacy like celebrities will also certainly have security using RID to track down any nearby drone pilots flying over and around and near their estates.
Yes, standing in an open area operating a drone makes one an even easier target for confrontation. However, flying from concealment while still continuously broadcasting your location via RID makes locating you equally easy from well beyond the range from which you can physically be seen, up to 5 miles away, with the right equipment.
If you are broadcasting RID, you are being watched. Just because they don't confront you doesn't mean they aren't aware of exactly where you are and where your drone is at all times. Raise their ire or suspicion and you'll soon see what happens.
If you
aren't broadcasting RID, you are even more suspicious to all the above.
Why do you think so many drone pilots have abandoned their previously carefree hobby, and decided it's just not worth the hassle any more, or they have instead scaled down to an RID free
