In the Controversial Case of R

In the controversial case of R. v. Singh, the Canadian Supreme Court held that:

B) at the time a person asserts the right to be silent, they can no longer be interrogated.
C) once a person requests an attorney, he or she can no longer be questioned about a crime.
D) police can continue to question suspects even after they assert their right to be silent.
