Plot Hole?
I can forgive all loose ends not being tied up (check out all the questions posed with regard to Mission Impossible 1) but, surely, if you have an organisation that enlists a dying man to assasinate the POTUS, that rents him an apartment in which to live while preparing for the assasination attempt and then has available enough survaillence equipment, operatives and weaponary to wage a small war, they would not leave the apartment intact with all the personal effects (cough medicine, painkillers etc) and then sit outside and just watch it?
