Wonder if anyone remembers that the Dred Scott vs Sanford decision states that...
“It would give to persons of the negro race, who are recognized as citizens in any one state of the Union, the right to enter every other state, whenever they pleased.... and it would give them full liberty of speech in public and in private upon all subjects upon which its own citizens might meet; to hold public meetings upon political affairs, and to KEEP AND CARRY ARMS wherever they went.”
A bad ruling can lead to all sorts of bad consequences.
