From the TSA Blog:
This past Wednesday, a Transportation Security Officer's search of a suspicious bag at Baltimore Washington International Thurgood Marshall Airport's C-Pier checkpoint yielded five credit cards and an additional driver's license... all belonging to different people, none of which belonged to the passenger. TSA contacted the Maryland Transportation Authority Police, who took the individual into custody.
This was probably a criminal. And yet -- letting the TSA say oh look, we don't like the looks of that, it has nothing to do with airline security, but let's get this guy arrested -- not too thrilled by that.
And then there's this.
