Germany: for white-collar crime, they'd usually arrest you by sending y0u a letter asking you to please come in. Even if she were guilty, she wouldn't be looking at jail time where it makes any sense for a regular person with family to try running.

Soeaking of idiots ruining their life: Assange might be a good example that people know. He was allowed to surrender on his own/with his lawyers (first time around). Not sure about his latest arrest, but IIRC he was resisting and all they did was humiliate him by carrying him out like a petulant child.
