Surveillance must increase after terror attacks, say 2016 candidates

Hillary Clinton, Donald Trump and others say new monitoring is needed following violence in Paris and San Bernardino - but they disagree on details

Presidential candidates from both parties came together at the weekend to call for beefed-up government surveillance programs in the wake of recent terrorist attacks in Paris and San Bernardino, California.

The candidates did not agree, however, on what kind of surveillance - new dragnet metadata collection, tools to fight encryption or some even more powerful capability - was needed.
