I hear alot on here about how the TSA should use the interview process for passengers and behavioral profiling for risk management. I have a question to proffer: Isnt this the ultimate form of discretion? There is a lot of talk about abuses of authority by TSA on this board. However it appears to me that using this method of risk management ultimately puts things up for grabs on the part of the screener making that decision. Retaliatory screening would still be an issue would it not?
