There are some very good responses is this thread showing restraint and due caution to the use of deadly force.
The Zimmerman Case going on in Florida is a good example of what one could face even when acting with in the law.
This is just a reminder below on the laws covering use of force in Washington State, reasonable, necessary, person [using][or][offering to use] the force may employ such force and means as a reasonably prudent person would use under the same or similar conditions as they appeared to the person, taking into consideration all of the facts and circumstances known to the person at the time of [and prior to] the incident.
Added emphasis is mine.
The ones responding in the video did a very good job, using a firearm would have endangered others in such close quarters as pepper spray would not be a good option, a hand held taser may have worked if simple restraining would not have.
