It has been explained that there is provision made in the Miranda law to temporarily suspend the law when there is danger of a cell or another individual poised to cause imminent harm or when the possibility exists that the individual has boobytrapped a location.

When that fear has been negated, then the individual must be read his Miranda rights.

Makes sense to me. In fact, it makes more sense to me than a rigid knee jerk law that takes no account of existing situations.
