Do you think TSA should be able to go through your checkbook?

I was reading this article and became quite sad.

The summary is: a woman tries to get on an airplane, TSA pulls her and goes through her purse. Then they start going through her wallet and checkbook. Then they decide she’s embezzling from her husband and call the police.

Do you think this is something that’s in the jurisdiction of the TSA? Would it affect your desire to travel by airplane if you knew the TSA would start rummaging around your receipts?

Do you think this might turn from an isolated incident to something more widespread?
