Interesting disconnect. I have seen no evidence that th Justice department wants to suspend the Consititution, What they want to do is preempt congress deciding that a need to suspends parts of the Bill of Rights, should the need occur. At this point I have seen no evidence of need, and declaring martial law is a rather easy thing to do in an emergency, without going through Congress initially. It can be done incrementally at the State, county, or municipal level each at their own initiative. If some elements feel it is unjustified, the solution is a court or a higher legislature.
