1. Legal viewpoint: what Richard S. said. This will be a lawsuit magnet if used.
2. Political viewpoint: Likely to be proscribed by the government.
3. Medical viewpoint: I would sure as hell be unhappy to try to treat a victim of this round, assuming he/she survived to get to the hospital...really nasty wound!
4. Personal protection viewpoint: Great ammo when survival depends on a one shot put-down, especially because it would appear that perfect shot placement may not be as necessary.
I'll be interested in the outcome.
