Approx 1/4 of the Earth's surface is land. Less than 20% of the land surface is urbanized. Thus, there's about a 1/20 chance of the the spacecraft hitting urbanized areas.

I worked on the recovery of the space shuttle Columbia that descend on East Texas and W Louisiana. Most of the artifacts we found were small and composed of a very lightweight alloy. Many large pieces were found in urbanized areas on top of buildings, even. Nobody was hurt and no structures were damaged.

The spy satellite is smaller and was not designed to re-enter the atmosphere so it doesn't have any structure reinforcement or heat shielding that the shuttles have. You could probably catch most of the pieces with a butterfly net without ripping the net.
