Twitter apps on mobile devices can surface near-to-you Tweets. This is incredibly helpful in emergency situations. A couple years back there were, literally, a dozen police cars on my street and traffic blocked in all directions.

He had a hostage and when he started lighting the apartment on fire, the SF SWAT team killed him. [0] More info on event from The SFist.
