Whilst this nay sound alarming, it is commonly available in fertilizer as previously stated. The fact that it was in pure form only means that a
terrorist would need about 900lbs of generic fertilizer (for the same amount, a good bomb making fertilizer has about 30% ammonium nitrate.
Ammonium nitrate has to be mixed with fuel-oil ( about 96%ammonium nitrate 4% fuel ) and then set of with a high order explosive ( TNT,PETN,RDX etc ).
A blasting cap just won't do.
I believe the Oklahoma city bombing was a 2 ton fertilizer bomb. So they are powerful, but not as much as military explosives.
