I witnessed this at the checkpoint in EWR Concourse A last night. Behind me in security was a guy, presumably from one of the stores behind the checkpoint that sells bottled drinks. He was allowed to place a tray full of bottles greater than 3.4oz thru the scanner, and bring it into the terminal.

What is the point of banning passengers from taking liquids through the checkpoint if store owners are allowed to bring them through by just putting them through the x-ray?
