Obviously the remaining killer and whatever support network he has need to be brought into custody as soon as possible. Equally obviously doing that without further loss of life is the ideal to strive for. However, does anyone else think shutting down the entire transportation network and asking people not to leave their homes or go to work is an over reaction?
It seems to me that it is an additional victory to bring one of the USA's most iconic cities and tourist hotspots to a standstill for....... how long?
Let's hope this resolves as soon as is humanly possible for all concerned.
