I doubt if your just doing a one off you will have any issue, but legally with the FAA you would not be in accordance with their mandates.

LEOs aren't the brightest bulb on the tree when it comes to "Drones" So things could get escalated, more than likely not...but you want to make sure you have the "i's dotted and T's crossed.
Your biggest issue is with other people who may have appropriate credentials observe you and question you as to what your doing on "their" turf and taking their business away...then things could get nasty...ask me how I know...it's a dog eat dog world out there.
