The airlines would be sued. However, there is nothing they could do if the majority of passengers all boarded carrying bags of pork rinds to eat as snacks.
This reminds me.
Thousands of flights were grounded on 9/11/2001.
I was of the opinion instantly that upon debarkation, all passengers should have been asked to eat a pork rind.
Those who refused would be photographed, fingerprinted and catalogued. How many "unsuccessful" killers of that day might have been caught?
I wonder how many future terrorists we might have nipped in the bud?
