Update - another officer has died.
"Three members of a U.S. Marshals Service fugitive task force were fatally shot during a standoff Monday while trying to serve a warrant in Charlotte. A Charlotte police officer died hours later from injuries he suffered during the incident. Four other law enforcement officers were wounded, and the person they were pursuing was killed.
The task force members were attempting to serve a warrant for possession of a firearm by a felon when they were met with gunfire at a Charlotte residence, police said." WP

From where I sit it looks like the Second Amendment is a suicide pact.
