I am no technophobe. I like being able to calibrate communication, depending on the situation - texting for the simple and immediate; email for business or when I want to put some lag time into the exchange; Twitter to promote something; Facebook to draw a crowd.

Maybe it's stress or anger or adrenaline or disillusionment or a bullying nature or simple fear of getting killed themselves, but there is a problem if a cop cannot tell the difference between a menacing gangster and the far more common person they encounter whose life is a little frayed and messy.

As long as anger, paranoia and misinformation drive our political debate, there are unhinged souls among us who will feel justified in turning to violent remedies for imagined threats.

Americans rightly, but sometimes excessively, celebrate every person in uniform as a hero, but seldom honor the difficult and often dangerous work being done day after day by members of our diplomatic corps. Warriors capture the popular imagination more easily than peacemakers.
