Your point is still well taken. Obama orders predator drone strikes that have killed thousands of men, women and children in Yemen, Pakistan and Afghanistan. Drone operators are told to look out for large crowds (schools, weddings, funerals, etc.) because only terrorists congregate in groups.
And we're either directly or indirectly supporting terrorist organizations in the Middle East, namely the Free Syrian Army, which have been going on rampages, killing civilians and making refugees out of millions.
Yet, Lanza (allegedly) murders 20 kids, and all of a sudden we have to have a "national conversation" about guns. We need an "international conversation" about our foreign policy.
