The Saudi government announced sharp cuts in spending and subsidies to cut the deficit in 2016. The deficit in 2015 was about $98 billion or 367 billion riyals , according to Al Arabiya Saudi news channel. In 2016 the budget is designed to cut the deficit to $87 billion or 326 billion riyals.

A year long study by the Washington Post of all shootings by the the police in incidents of law enforcement in the U.S. shows only about 4% of the incidents involve police killing unarmed black persons. Yet a disproprotionate number of unarmed men shot are black or Hispanic- 3 of 5 people. The large majority of incidents involved people who were mentally troubled most of whom carried a weapon, persons carrying a weapon, or persons running from the police when asked to stop. The WP has compiled every police shooting in its database for analysis, something even the FBI does not have and is only now starting to put together.

Mearkle was acquitted by the jury.
