While there remain some mysteries linked to the hellish massacre at the Pulse gay bar in Orlando, one thing was clear -- the man who kept pulling the trigger wanted to make sure that it was impossible for journalists around the world to avoid putting religion in the lede.

In the past, journalists have often had to wrestle with vague allusions to the names or nationalities of the terrorists involved in this kind of incident, while cautiously searching for on-the-record information that might point to motivation.

With his mobile call to Orlando's 911 center, Omar Mateen settled that issue, claiming that he was acting out of loyalty to the Islamic State.

But you knew that already and that's my point. It's hard to find a lede this morning that doesn't include a direct reference to that call.

So it's no secret why Mateen did what he did, at least according to whatever logic was functioning in his head at the time he marched into that nightclub. In this terrorism case, reporters could move straight into the second layer of mysteries about the man and the details of his life and faith. While President Barack Obama kept his language vague, other political leaders were quite blunt. The New York Post noted:

Mateen “made a pledge of allegiance to ISIS,” California Rep. Adam Schiff, the top Democrat on the House Permanent Select Committee on Intelligence, told CNN.

Schiff said the timing and target of the attack can’t be a coincidence.

“The fact that this shooting took place during Ramadan and that ISIS leadership in Raqqa has been urging attacks during this time, that the target was an LGBT nightclub during (LGBT) Pride (month) and, if accurate, that according to local law enforcement the shooter declared his allegiance to ISIS, indicates an ISIS-inspired act of terrorism,” Schiff said.
