In the series "The Wire" there's a conversation between the mayor and the police commander that goes like this:
- Can't you have police sit on locations where the homeless gather? Monitor them like that?
- And still answer the calls? Not without doubling up post units, which means overtime.
- Overtime, again.
- Blood in our veins, Mr. Mayor.
That's an interesting expression; I haven't heard it before.
My guess is he means his staff are not superhuman and can only do so much, but I'm not sure. So what does it mean? I couldn't find anything relevant googling the phrase so I'd also be interested if you know of any references.
