Cell phone service is a lot more fine-grained than you think, especially in old buildings with thick walls full of important people who insist on being connected all the time. Check out how The Washington Post described it:
The Capitol, more than most buildings, has a vast cellular and wireless data infrastructure of its own to make communications efficient in a building made largely of stone and that extends deep underground and has pockets of shielded areas. Such infrastructure, such as individual cell towers, can turn any connected phone into its own tracking device.
Phone records make determining the owners of these devices trivially easy. Congressional investigators and federal prosecutors can also identify devices and users who may have connected wittingly or automatically to congressional guest WiFi networks ā unless rioters made a point of deactivating their devices or leaving them behind during the takeover.
So no, Iām not saying we should conclude that everybody in DC was an insurrectionist. Iām saying we should conclude that everybody who was inside the Capitol was inside the Capitol.
