If I was a billionaire, I would set up a fund to pay every single cop salary so they can walk off the job for a month including legal to keep them from being fired. Prolly have a goon squad to discourage scabs too
36K police X 6K per month average salary = 216 million for one month's salary alone.
That is over a fifth of your billion.
Still, with lots of friends on the force, you might be able to recoup it...
