Try to keep in mind that you are not the barometer of what others are doing. You may use your phone to take a picture, but that doesn’t mean everyone does that. You may have left television behind, but most have not.
And not everyone wants to rely on one connection to an Internet provider for all their information and media because when that connection goes down, you lose everything.
So what should have Boston done, not knowing where the guy was or if there were more explosives in his hands? Would you be willing to risk a family members life just so you can pretend it’s a normal day? I am sure most people didn’t mind having a day off work.
