Why Does Obama Need A FORTRESS in USA?

WOW!  He not only has a wall but check this short video out that shows what he has.  Why does he need such a fortress?  Do all former presidents have such a fortress. Well Bushes have a compound but its in Paraguay!  What is he planning? 

CIA Mockingbird Media claiming President Trump is lying about Barry’s 10’ WALL around his mansion is showing the masses pictures of when it was first purchased NOT what it is after he turned it into a FORTRESS & WE TAX PAYERS pay for this exhobinat security…why does he need it?  Does it have anything to do with the fact he said he was going to have HIS OWN ARMY when he was president & we paid for it!
