I guess the bottom line is safety is mainly about your state of mind. If you feel safer by covering your tag then do it. If you have guns and dogs to make you feel safer that works. But to help you feel more safe, I can assure you people don't make you a victim by seeing your tag on the internet. Its kinda like the movie "The Jerk" with Steve Martin where the crazy guy picked his name out of a phonebook then went to kill him. Funny story but it don't happen. Now if you were a celebrity you may have a nut try to locate your house by using the tag. But you have nothing to fear.
