Is this written in your SOP? If so, great - I will be targeting that as part of our anti-TSA lobbying efforts. The TSA is not permitted to make up laws which are not germane to the scope of their authority. Carrying cash in ANY amount is not illegal - and any 'suspicion' resulting from your finding of said cash is so far outside the scope of your search, I will ask our legislators to order TSA management to remove that from your SOP.

If it's not in your SOP, I will ask our legislators to question Kippy during his next appearance why his staff seem so interested in reporting cash when they seem so unable to find guns, knives and bomb parts.
