"We know that we have the same bomb maker, or different bomb makers are using the same instructions".
Then the rows of different bombs begin: there are the cleverly camouflaged ones, intended to take out a single victim, then others designed to maim and kill more widely.
"Yesterday, within a 12-hour period, we had 90 different bomb threats or scares," Police Commissioner Bernard B. Kerik said yesterday in an interview, drawing a sharp distinction between the two.
In the centre of London, fire engines were cruising down streets and dozens of police cars, with sirens blaring and blue lights flashing, were rushing to the different bomb explosions.
While they were still at home, fighting against the forces of President Bashar Al-Assad, the family moved between different bombed-out apartment blocks in a once middle-class suburb of Aleppo.
To ground-truth these analytical techniques, researchers at Livermore and other national labs are producing surrogate fallout representing different bomb types.
The glass varies with the explosion site, but different bomb specs also produce unique melt glasses, providing clues about what happened.
But if there is no proximate danger of highly indebted eurozone governments, like Italy's, being deprived of the life-preserving loans they need, if the potentially explosive financial pressures aren't as powerful as they were, there appears to be a different bomb ticking away.
