Tell me the difference between your arguemments and those that they use against the 2nd? You use the justifications Security.
You look at that picture and tell me who are those people at that moment more affraid of the terrorist or the police?
Of course people were afraid.
A homicidal islamist terrorist was loose in a residential neighborhood. Earlier that night he and his brother had carjacked, robbed money, and murdered a 26-year-old MIT cop named Sean Collier. Something on the order of 200 rounds were spent. The younger brother actually killed the older brother by running him over in the street to escape from the cops.
Then the next day, paramilitary police roamed several blocks of the residential neighborhood searching door-to-door for the islamic terrorist, who, we have every reason to have believed, would have been perfectly content to go out in a blaze of glory.
Of course people were scared. The whole effing day was unsettling. The whole week was.
And you're latching on to this fear to make political hay.
