Posse Comitatus is No Obstacle

This is what the Heritage Foundation is saying, that we shouldn't change the law, but adapt the military to deal with homeland disasters:

the Posse Comita­tus Act has never been a serious obstacle to using federal forces to support domestic operations. For example, federal forces helped to quell riots by miners in Idaho in 1899; protected James Meredith, the University of Mississippi’s first black student, in 1961; assisted in controlling the 1992 Los Angeles riots; and helped to reestablish order in the aftermath of Hurricane Kat­rina. In fact, federal forces have been used to enforce laws over 175 times in the past 200 years under the authority of laws such as the Insurrection Act.
...Deploying the military faster—making it a more agile and flexible instrument to respond to all kinds of domestic security needs—is a question of force structure and policy. It does not require tampering with the sovereign responsibilities outlined in the Constitution. There are better solutions.

They go on to offer solutions, my favorite being a Navy National Guard:

Creating a Navy Guard to include all coastal states would offer several advantages. A Navy Guard would provide coastal states with more resources to address their state maritime security and public safety requirements. Unlike the Coast Guard, the Navy Guard would focus on state needs when not on active federal service. It would also pro­vide an organization within the National Guard and the Navy that treats homeland security missions as an inherent responsibility and would work to develop the requisite competen­cies and capabilities to fully support these tasks. Finally, a Navy Guard would provide a suitable partner for the U.S. Coast Guard to ensure seamless integration of daily DOD and DHS maritime operations.
