So who else uses similar standards? Public transit such as bus and train systems (trains probably covered by separate or additional such as DHS even if part of local transit), law enforcement etc?
Foriegn terrorists or now domestic threats also?
Arrogance? Penetrating stare?? Inappropriate dress? Complaining about screening process? Wtf?
So this means that if you're not conforming to very stringent norms or if they simply don't like you you can be profiled endlessly.
And if somebody in power wanted to give you a hard time do the corruption a frame up or just the fact that they don't like you or your threat to the status quo Etc this could be completely misused and utilized as a tool of corrupt power for abuse of power.
When did the checks and balances and oversight vanish that took into account the reality of human animal nature and potential for abuse of power?
