Looking at a pizza company or a building it's anyway of conducting an investigation. You have to look at who is involved with the children being abducted. In this case with regard to the pizza company that would be James Alefantis who owns these places
It is quite a leap from Laura Silsby to the DC pizza place.
BTW- Did Edgar Maddison Welch while he was running around the pizza place pointing guns at people and firing his weapon in a crowded restaurant find any victims of child trafficking or evidence that child trafficking was being organized out of the pizza place?
If not, why not?
