It looks like they are taking captured civilians and/or suspected Hamas to a staging area, protected from gunfire, to be processed or questioned .They are likley blindfolded so they can't say where they were once they are released.
There is no indication that they are inspecting the building or using the civilians as shields..
Loving the app so far. Is there anyway to view communities by size? My instance has a "communities" page that shows local and all communities by user count. Is this on the roadmap?
