Not true. Carrying very large amounts of money on a plane, esp. one leaving the country, is a legitimate issue of concern esp. since drug dealers/couriers/contacts can claim it is only for business deals (since they have not drugs on them).
If the dog signifies that it detects something of interest, then the bags and person can be searched. My son was an explosives K9 officer for the federal government and the dog’s nose was 1200 times more sensitive than almost any other dog (It was a Belgian Malinoise. Better than a German Shepard).
Also, there is a type of cash carrying limitation above $10,000 under certain conditions. Don’t have the details in front of me.
This guy didn’t hit the lottery, believe me.
Need to know his name, city/state/country of origin, where he was coming from and going to, had he done a significant amount of overseas or out-of-county travelling (Canada, Mexico) in a discernible pattern, etc.
This is a story worth following and writing about.
Lacking this the person has the right to carry as much cash on his person as he likes and tell the cops to mind their own business.
As is pointed out he could not have been leaving the country, which is the only way it is illegal to carry above $10,000 in cash without declaring it because, if he had been leaving the country they would have arrested him for that.
They did not.
I do not give a rip how sensitive the dog's nose is, they can not sniff out a crime here when there is no crime.
