Does anyone else think those photos look like a photo from a drill?

Some of the people on the pews appear bored, and just kind of leaning forward.

There's two "shooters" dressed in black masks and pajamas. And another character who appears to have a firearm.

It doesn't look like it's in the middle of a firefight. More like a snapshot of a drill.

(Update): According to the Washington Examiner, “Witnesses said they saw the gunman shoot someone with a shotgun during communion, which prompted another parishioner to shoot him. However, some outlets reported that an armed security guard ‘subdued’ the suspect.”
