I am assuming that these photos, as Dio suggests, are from about 1700 EDT in Albany, NY. Fairly warm for August, so why the baggy clothing?
I took the liberty of having The Missus assume the pose of the "woman" in the shot. The grip on the purse with the right hand is perfectly natural stance, consistent with a woman carrying her handbag.
The shape of the left side, however, is indicative of something being carried under the arm, or slung over shoulder - a backpack, or similar item.
Also, the left arm is positioned to look as if "she" is holding the arm of the man in the white coat, as if he's escorting "her".
The shape of the head scarf, and the rest of the outfit, is not laying properly for normal fabric; there is SOMETHING being carried underneath.
Surface-to-air (SAM) systems, even Man-portable Air Defense Systems (MANPADS), are bulky things; the SA-18 comes to mind; it's enormous when it's deployed for use. The bulges, the person's stature, all lead me to conclude it's NOT a fully-deployed MANPAD. It COULD, however, be the components of a full system - the guidance package, possibly.
It could also be a broken-down rifle, or similar weapon; the stock assembly and breech, perhaps. The shoulder straps would still be attached in that case, making for an easier carry.
A third scenario, would be a large backpack arrangement, which could carry a number of small items easily concealed. THIS IS THE MOST LIKELY, IMA...
What we are most likely seeing, is a delivery; we can speculate as to what (ordnance, weapon parts, etc.), with varying success. But there have been disjointed but numerous reports of using women as couriers - they can pass thru checkpoints easier than men, and with Sharia law, they are not to be noticed.
Yet another tactic from an adaptive foe.
