In reality, photographers seldom get sued. And the rare times that they are, the case usually ends up targeting not the photographer, but the publisher who used the picture, either unwittingly or purposefully, in a wrongful manner. Because they don't have deep pockets.
Attorneys know it is wasted time to go after a target whose assets are minimal.
Armed with this information, photographers who are intent on capturing the world around them on film should be less timid in pursuing their mission.
