316 people are shot or killed every day in the United States.
At 5 humans attacked per day per zombie, it would take 24 days
for 316 zombies to overtake a population of 7.9 billion.

"Tad Spector at your service!"
I remember vaguely a week ago talking to the President on the
phone.
"Look Tad, I heard you were the best. I need you on my team,
on my side. You hear me. I need a guy that's not a part of the
system."
Seemed a bit paranoid at the time. But now he seemed even
more suspicious.
"They are after me, Tad. You can keep a secret right. I mean
that's your job."
