Very few people know what a BDO is or does. So intimidation is not really a factor. As far as harassment, well most folks here would say that an odd look is harassment. So I hope you don’t mind if I take that with a grain of salt, or two.
The harassment I'm talking about is the real intimidation that real people feel when confronted by someone looking very official in a police-like uniform. Kippie himself stated that the blue uniforms and shiny badge were designed to command public respect, or something close to that. "Commanding public respect" is a codeword for raising the intimidation factor. I've got to believe that anyone except the most seasoned FTer (like a lot of us) would believe that they are in some kind of trouble if anyone in a TSA uniform starts questioning them and risk arrest if they don't answer all his or her questions.
