If it was a federal offence, they would be charged. Have they been charged with a federal offence? No. Because they didn't commit one. The aircraft was still at the gate.
Next you'll be trying to tell me you are interfering with the safe operation of a flight if you are late to board, thus delaying the aircraft.
You really are grasping at straws, I did not mention federal offences or that they had commited one, or are you trying to imply you need to have committed one to go on a no fly list?
No I will not be telling you a late passenger is interfering with the safe operation of an aircraft because they are not, the power is squarely in the Captains hands, you offload there bags and go without them!
