Story is now that gun was found during the normal security screening to enter the concourse -- which means the headline of "Trying to Board Flight" is completely wrong.
The entire statement from the Harris County District Attorney's Office reads as follows:
"Under Texas law, a person commits an offense if the person intentionally, knowingly, or recklessly possesses or goes with a firearm, illegal knife, club, or prohibited weapon in or into a secured area of an airport.[1] It is not enough to simply prove that the person possessed the weapon -- Texas law also requires a prosecutor to prove that the person was aware he or she was in possession of the weapon.
"This awareness is evaluated on a case-by-case basis by screening prosecutors. In each case, the prosecutor deciding whether to file a criminal charge pays careful attention to the observations of the arresting officer to determine whether there is direct or circumstantial evidence showing that the person was aware that he or she was in possession of the weapon. Factors considered by the screening prosecutor include the statements and demeanor of the suspect, the location and size of the weapon, and the reasonableness of the suspect's claims that he or she forgot about the weapon when entering the secured area.
"Effective screening at airports remains a high priority for safe travel and this office aggressively prosecutes people who knowingly bring weapons to airports. This office will not criminally prosecute people who make innocent mistakes, however. This has been the long-standing policy of the District Attorney’s Office and is consistent with our duty to see that justice is done."
