How does the Supreme Court incorporate the Bill of Rights into state law?

Answer:
They don't. The 14th amendment does that, in its first clause, by providing that

"No state shall make or enforce any laws which shall abridge the privileges and immunities of citizens of the United States..."

In other words, those privileges and immunities guaranteed in the Bill of Rights.
