And by the way, even if the suspect is guilty, he/she might be a small cog in a much bigger engine, and by doxxing him/her the minds behind the fraud would be alerted then enter lowest profile mode, shutting everything down and making them extremely difficult to capture.

Doxxing can be a good thing only when authorities can't be trusted, which is the case for example of police violence and racism, where they're clearly protected by a corrupt system; in this case making their actions public becomes a public service. But in the above and other similar cases, think twice before publishing information that could undermine an investigation, even though they're properly checked and accurate.
