How do you know there was a single fugitive? I guess you're just smarter than all of the law enforcement in and around Boston.
That is not a high bar.......FBI has interviewed the older brother.....no connection.......Holdback a full day to release clear photos of perps.......You think all the people calling who recognized the perps would have a response sent to their homes......nope.....clueless.....instead they hijack a car, take his debit card to get money, and then let him go......a common criminal act, and from that act they ping the cell phone......an officer follows.......gets shot at.....they kill the one brother and let the other get away.....but it gets better.....they find the car and a blood trail.....no dog.....but they put 1 million people in a metropolitan area under house arrest, all the while drawing a perimeter which is too small as the perp sits in a boat for almost a day, before finally folks are let out of their house arrest, and a person discovers the perp.......
So you are right.....these folks did not know who the perps were....they did not know how many.....they appear not to have known a fricking thing......so forty or fifty million of economic damage is done to a major metropolitan area, and the prototype for future soft attacks has been created......not by terrorists, but by the very folks who over reacted and did not protect the citizens with the same protocols which are used in major events where unattended bags are to be immediately reported......gee.....I have been to events which it is posted and you are reminded.....do not leave unattended bags, and report the same.......but this standing army busting into citizens homes and marching them down the street like they are the criminals......well any objective look at what happened is a huge fail.....and when we cannot even discuss that fail.......without somehow being unpatriotic or unappreciative of our LEO.....well, that is the key to future attacks.
