A prominent anti-gun crusader called out the National Rifle Association less than two hours after an active shooter was first reported at an Annapolis newsroom.

Five people were reported dead at the Capital Gazette building, and multiple more were injured.

Moms Demand Action founder Shannon Watts used the tragedy in an attempt to debunk a tweet the NRA put out earlier in the day.

“An armed man is a citizen, an unarmed man is a subject,” the NRA tweeted, which included a 17 second montage of newspaper headlines illustrating times that firearms deterred crime or saved lives.

Watts replied hours later, tweeting “Today an armed citizen killed unarmed ‘subjects’ in their workplace in Annapolis. See how that works, @NRA?”

At the time of the response, much information had not been released about the incident, including the shooter’s motivation. (RELATED: Shots Fired In Maryland Newsroom, Multiple Fatalities Reported)

She also used the tragedy to promulgate her anti-gun agenda by encouraging action.

Watts is an avid NRA critic. She frequently tweets to or about the gun rights organization.
