Lumpyoatmeal saidSeems like homeland security ought to be a sub-department of the FBI since the FBI is essentially our national/federal police.
"National/federal police" is something you didn't think too long about before you came up with the idea but you aren't the first one to come up with it.
If Homeland Security were to disappear (which it won't) we'd never miss it or be in any greater danger because of it. There has been nothing done by HS that hasn't been, or isn't already done my city, state police, FBI, US Customs and Border, Coast Guard, Immigration Custom Enforcement with intelligence from the CIA and Pentagon. In fact everything that Dept of HS is supposed to do was previously done by all the departments listed above. Most of the work credited to Homeland Security is really done by the same people who've always done it.
