Oh, you thinking the January 6 prisoners? 

So how did they track them? What sort of security does the Capitol have? Who directed the Sargent at Arms? How do the magnetic doors operate? Why did they not show the front camera shot of the supposed "bomber?" Why did Pelosi and Bowser not request the National Guard? 

That entire building has multiple types of cameras throughout the entire building to include thermal. They run a cell buster and all communications is monitored through their network taking cell phone, SEID, EID, IMEI, wi-fi and Bluetooth addresses. The system logs those numbers for geo-fencing tracking supposes. 

Shall I explain more?
