See Something, Say Something. . .

"What can I do" is the question people might ask.  I say might, because many go through life in a state of normalcy bias, without seeing much of what is seen or unseen.  But the question remains.  See Something, Say Something simply did not apply in this San Bernardino action. Why? Societal castration?  Perhaps, more likely cognitive dissonance resulting from normalcy bias.

From our friends at WikiPedia:
"People with a normalcy bias have difficulties reacting to something they have not experienced before. People also tend to interpret warnings in the most optimistic way possible, seizing on any ambiguities to infer a less serious situation."

Leon Festinger's theory of cognitive dissonance focuses on how humans strive for internal consistency. An individual who experiences inconsistency (dissonance) tends to become psychologically uncomfortable, and is motivated to try to reduce this dissonance—as well as actively avoid situations and information likely to increase it

See Something, and then subconsciously say no I didn't see that.  In that state there is nothing that person can do.  Is there?
