Now is a good time to remind people to never ever agree to a police search. They're gonna phrase things weird and take advantage of your good nature. Never agree to any sort of search.
Hell, even if they have a warrant I'm tempted to explicitly say I don't consent. I'm not going to resist but I'm gonna make it clear I'm not consenting. Because how the hell do I even verify a warrant is real? I have no idea, and I certainly wouldn't be able to find out if they're at my door.
Be aware though, in Georgia there is "implied consent" with regards to roadside breathalyzer tests. If you get in that situation, remember I'm just a random lemming and not a lawyer. Other states might have similar things.
