This could very well happen in a number of situations.
Cop is at your door for what ever reason. Loud music, dog barking, boat parked illegal in front of your house that is a neighbors friends boat spending the weekend over, etc., ect. Your smoking a J and a cop shows up at the door and you answer. He asks you if that is Pot he smells. You say no it is not. He then requests to come into the house. You ask for a warrant. He says I will have one in 5-10 minutes come outside please and let me tell you your rights. You slam the door, lock it and have 2-5 minutes before he recieves approval via internet and back up......Now what??????????
