When the abortion clinic in the south was attacked a few years ago, the bomb was no more menacing than this one, but I’ll bet you don’t find one reference to it as ‘small’.
What I object to is the overplay with regard to one incident and the downplaying of another.
The recruiting office was not a ‘protected’ target. Thus it’s attack was small. The attack on the clinic was serious and a real threat.
That’s my take on it.
From the MIT Tech newspaper:
Anti-Abortion Take Religious Violence in America to New Lows
Earlier this month, an abortion clinic in Newport Beach, Calif., was damaged by a small bomb and its manager said she later received a telephone threat that her car and house would be next.
Admittedly, this was the only relevant media reference to "small bomb" in a cursory web search.
