They also had less historical precedent for bombs going off preceding an armed terrorist attack, or a larger "double tap" follow-up explosion. Additionally, the low explosive gunpowder used in these bombs is considerably less powerful than what you'd encounter in a modern day terrorist attack using high explosives (e.g. TATP, PETN or RDX).
