Sitting in the public area before security at CLE I noticed a few bags wedged under a seat. I moved Mrs EW away from the area and mentioned it to the TSA guy.He said to "not worry" as it was the guys from kerbside check in who had "probably" left them there
As a native of Northern Ireland I remain unconvinced that this would not be a breach of "security".
As an aside they went through me for a shortcut in security as I was travelling alone on a one way ticket.
