Now that all 50 states have concealed carry. You are likely to be surrounded by far more guns than you could ever have imagined. A properly concealed weapon is almost impossible to spot when you aren't looking for it. Most people are never 100 feet from someone who is armed. In addition this just goes to show how pointless it is to try to keep the good guys from being able to carry safely as any criminal can pack the same amount of heat just as undetectably.
