This reminds me of the incident at HOU a number of years back. Thankfully, the Houston police officer (and the FBI) didn't see an issue, although the TSA pushed it, which resulted in Mr. Bataineh losing his job that the FBI called "a non-event", the FBI taking his laptop (not sure when or if he received it back) and being placed at least temporarily on a list of terrorists based on a TSA report.
