Keep in mind, driving around a parking lot next door is in no way helping Jordan Davis as he bleeds to death. Or, if he died instantly, I'm not thinking this was a car full of pre-med students or something... they had every reason to believe he needed to get medical attention immediately.
So, how does circling a parking lot then driving back to the gas station help their friend who just got shot?
Driving off to try to get to a hospital ASAP is one thing, and would be completely understandable... driving to a nearby shopping area and doing some circles of it's parking lot THEN returning to exactly the same parking spot at the place you were before, and apparently (if the other poster who said this is right) lying to police about this later?????
FISHY. AS. FUCK.
If it can be shown definitively that they lied about driving off and coming back, to cops... I would consider that almost as good as finding the shotgun. Which they will never, ever do.
Those guys came back that night and fished the damn thing back out of the bushes or trash can they tossed it in before cops ever heard that they should even be CONSIDERING searching for such a thing there.
