From Potter's Field

'She can't,' he simply said. 'And she can't stay with you in Richmond. To tell you the truth, she really can't stay anywhere right now but here. This is where she's safest.'
'She can't stay here the rest of her life,' I said.
'Until he's caught…'
'He may never be caught, Benton!'
He looked wearily at me. 'Then both of you may end up in our Protected Witness Program.'
'I will not give up my identity. My life. How is that any better than being dead?'
'It is better,' he said quietly, and I knew he was seeing bodies kicked, decapitated, and with bullet wounds.
I got up. 'What do I do about my stolen credit card?' I numbly asked.
'Cancel it,' he said. 'I was hoping we could use money from seized assets, from drug raids. But we can't.' He paused as I shook my head in disbelief. 'It's not my choice. You know the budget problems. You have them, too.'
'Lord,' I said. 'I thought you wanted to trail him.'
'Your credit card isn't likely to show us where he is, only where he's been.'
'I can't believe this.'
'Blame it on the politicians.'
'I don't want to hear about budget problems or politicians,' I exclaimed.
'Kay, the Bureau can barely afford ammunition for the ranges these days. And you know our staffing problems. I'm personally working a hundred and thirty-nine cases even as we speak. Last month two of my best people retired.
'Now my unit's down to nine. Nine. That's a total of ten of us trying to cover the entire United States plus any cases submitted from abroad. Hell, the only reason we have you is we don't pay you.'
'I don't do this for money.'
'You can cancel your Amex card,' he said wearily. 'I'd do it immediately.'
I looked a long time at him and left.
