Let me try this sloooowly for you.
I do realize that the laws have been found enforcable and Constitutional by courts.
But I: (1) disagree with some of those interpretations; (2) disagree with the legislative premise behind those laws, i.e. dogfighting is equal in the eyes of the law to manslaughter; and (3) think the U.S. attorney has better things to do.
That said, I believe a Virginia jury, whether Federal or State, will not convice Vick for this. Ergo, justice prevails in the end, putting aside the wasted expense and resources and abuse of discretion by the U.S. attorney (see Barry Bonds perjury/obstruction grand jury and Greg Anderson's continued incarceration for contempt), despite the existence and enforcability of said laws.
Less (I worry that, even now, the length of my final sentence may deter your comprehension) inSF
