I still think Jeb should've taken action first as it happened in his backyard. However, since he did nothing, I agree the President should have done what you suggest.
The argument holds for both the state and Federal legislative and executive branches. In both cases, two branches were in agreeement as to the action to be taken, having passed laws to the effect. The judicial branch resisted, and the local cops knuckled to the judge. Jed could have sent in the state police----GW could have sent in Federal marshalls.
