The first one was found at 8am. As they proceeded to find more all day, they didn't know what they were dealing with. Could there be 10 fake "bombs" & one "real" bomb? What if they didn't get to it in time?
It wasn't until almost 5pm that Turner stepped forward with a statement that they were sure what was going on.
I say...better safe than sorry AGAIN. How would Boston look if they let it happen AGAIN?
