Airport security staff tend to be very strict when removing dangerous items from luggage, with good reason. For example, TSA guidance is very clear: If prohibited items are found during security checks, they won't be returned to their owners.

Yes, the TSA (Transportation Security Administration) has the legal authority to open and inspect any checked bag that triggers a security alert during the automated X-ray screening process. If your bag is selected for a manual search, a TSA officer will open it and may remove items to inspect them more closely or to resolve a "threat" detected by the scanners. If they do open your bag, they are required by law to place a "Notice of Baggage Inspection" slip inside the suitcase to inform you that it was searched. In 2026, the most common reason for an inspection is the presence of prohibited electronics or certain high-density food items that appear suspicious on the scanners. The TSA may "confiscate" items that are strictly prohibited in checked luggage, such as loose lithium-ion batteries, power banks, or certain flammable materials (like lighters or spray paint). These items will not be returned. To ensure your bag remains secure, it is highly recommended to use TSA-approved locks, which allow officers to open the bag using a master key rather than cutting your lock or damaging the zipper to gain entry.
