Homeland Security and the TSA duplicate the Coastguard.
Our Coast Guard is part of homeland security/HSA.
We and other members of our family know Coasties, active and retired, who went into HSA.
Most feel good about it.
The Coast Guard prior to 9/11 and the formation of DHS was under the Treasury Department in peacetime, and under the Navy in wartime. It should be under the Pentagon as a separate service. That is where it would serve best and be properly supported.
