If your public enemy like him, and want to deter people from attacking you... Why not advertise "me and everything i love is a fucking fortress, good luck, fuckers!"
Maybe not the best thing to do, to not stir up, but defiantly, the more intimidating he can make himself, the longer he will live. Personally, if i were him... I would not have stayed in the united states very long after trial, maybe swung by a gun shop or two, a mc donalds, grabbed the family and left for the airport.
In some instances, exile is the only way to avoid an untimely death.
