who exactly are they looking for? in your informed opinion
"law enforcement officers conducted a nearly 24-hour door-to-door manhunt for Dzhokhar Tsarnaev, who is suspected of helping his brother plant two bombs near the finish line at Monday's Boston Marathon that wounded more than 170 people and left three dead.
Officials announced at 6:00 p.m. news conference that they had been unable to apprehend the suspect, despite combing through a 20-block area of the Boston suburb of Watertown"
I'm with Gewher on this one. Why are you being intentionally- well, I'll just say "coy"?
Are you trying to prove that these intrusions are OK if they are or are not looking for the boston bomber in an area that is or is not Watertown?
I really fail to see what distinction you seem to perceive there.
