I've been checked at airports before and I have no problem with airport security either. Terrorism or crime are real threats and police without technology is just as biased if not more so then machine aided ones.
The minority report fears every time technology is introduced to policing is an abstract and slightly silly complaint given that most police brutality and abuse of power occurs in impoverished, low tech areas, where if anything police has fewer tools and force available than in public airports and surveilled neighbourhoods.
