Or, you could run the official government protectors out of budget, then "magnanimously" offer to pay for security personnel out of your own budget (but of course they'll need all the same legal privileges that the official guys have, 'cause they're protecting the president and all).
If I thought these clowns were capable of that level of planning, I would be even more afraid than I am now. As it stands, I am willing to consider the budget thing to be pure, narcissistic obliviousness to reality. And greed. Lots of grifter greed.
