Explanation

If you're unsuspecting, you are innocent and trusting. An unsuspecting tourist will be blissfully unaware that the smiling old lady on the subway has stolen his wallet. If you lack a sense of suspicion or distrust, especially in the face of some kind of danger, you're unsuspecting. A criminal's unsuspecting victims find themselves utterly surprised that they've been robbed, and an unsuspecting hiker wanders right into a bear's den. In both cases, a little bit of suspicion would have served them well.
