I trust the abilities of our law enforcement officials...

Read on another post that instead of calling for a roadblock 15 minutes after the shooting the police should contact all radio stations and tell everyone to pull over to the side of the road instantly. Tell people not to leave their houses for work, etc.
Course the killer will do the same, but it would give the police a chance to setup a roadblock that might actually do some good.
