I have been on hiatus for a month but this has gotten me so angry I have to write....

The NRA has once again stopped the most FUNDAMENTAL background check for owning an assault rifle---no doubt with many fence-sitting GOP senators hoping the front-page publicity of this awful terror attack will shield them from potential fallout.

The same day that the NRA's GOP minions decided that it was okay for a violent criminal to shoot me in the face, I discover that the Boston investigators are blocked from doing a thorough investigation because of the NRA and their allies.

Identification taggants are used to make it possible to trace explosive materials after detonation back to the source of the bomb. It is simple, cheap, and allows tracing to a point of sale. Law enforcement, the ATF, and others have pleaded for it. Clinton tried to make it mandatory after the OK City bombing. Current experts say it would have helped with the current investigation.

WHO would POSSIBLY oppose this technology?

The same idiots who oppose a background check for a killing machine....
