And in headlines: The Israeli Supreme Court ruled that ultra-Orthodox Jewish men must enter the military draft, Wikileaks co-founder Julian Assange pleaded guilty to one felony count of illegally obtaining and disclosing U.S. military secrets, and the U.S. surgeon general declared gun violence a public health crisis.
