Yea man...I think that you are paranoid. The cop probably isn't too concerned with every person in the neighborhood. For all he knows, you are just some dumbass who leaves his light on in the basement. Plus, he probably doesn't even look at your house. And if he does, he won't give it a second glance. Seeing some light coming from a house doesn't raise the alarm. That would be for some cheesy TV show shit, where the cop gets a "hunch." Don't worry. Your cop won't get a hunch unless you give him one.
