Given the pure fact that new information is still coming out, it isn't feasible to compile a realistic psychological profile on this guy and argue that he was mentally sane.

Unless we're clumping together issues of race-tolerance, racial-profiling, and racism into the term "political correctness" which I'm not sure is quite correct.
These are some examples of political correctness I found from Google:
