Nobody is really safe as such. There are criminals who will blow you away because you didn’t have much money when they held you up. You might be under the microscope of groups like the FBI because some neighbour said you were acting suspicously.
You could find yourself out of work tomorrow for variety of reasons and your life style rapidly starts shrinking out of sight. Assurance plays on your fears and so does advertising! In short, if you start worrying about your safety, you could rapidly become paranoid. You just have to assume that you are safe and keep going as if it were true.
