From previous reporting about this testimony:
> Jackson, who was testifying via Zoom after just getting out of the hospital, said that he was leaving work one morning when he saw security guards approach the mailbox. He proceeded to watch them open a large box at the bottom of the mailbox labeled “1P.” While it was dark at the time, Jackson said his headlights illuminated the area, so he was able to clearly see what they were doing.
Anyone who's lived in an apartment building would know this was a box for incoming mail, but I wouldn't be surprised if single family housing was the norm around the warehouse.
