hey whats up yogi ,,if the cops knock on your door and you do not answer ,as long as they do not smell pot you would be ok ,,if they smell pot they have reasonable suspicion that a crime is being committed inside,(pot smoking ) they would have a legal right to bust open the door ,but they would risk alot ,,a good lawyer could say how could they proof the smell was coming from your house ,maybe someone walk by smoking a joint ,they would probably make a good show for who ever called them ,but in the end would leave ,,,,,,but be careful get a cop with an attitude and you could have a problem ,,anyway good luck ,,stay true as always PEACE,LOVE,RASTA
