Airlines keeping planes fueled at Sea-Tac despite Olympic Pipeline shutdown

The passenger’s luggage tripped security in Tulsa, and so Pinnacle security detained it. However, the passenger who owned the luggage was free to travel to his destination.

However, this is what is unclear to me:

The bag flunked, and stayed in Tulsa. The passenger, however flew to Memphis, although his luggage was arrested (explosives detection.) Shouldn’t they have taken him off the flight with his luggage?

So after he arrived in Memphis, law enforcement interviewed him, and he passed. But they’ll be shipping his luggage to him later. Does something seem strange here?
