>But is it a common sentiment that you can be charged with anything by a district attorney?

Pretty much. If you piss them off enough, or if they are trying to get elected to something else and think you are a good way to do it, then yes, they will charge you with something and keep going at it. (See: Aaron Schwartz).

It's not "anything", it's "intent to defraud". The prosecutor needs to provide a minimum standard of evidence to bring charges, they don't need to prove intent (to hear the case). The rest is like I said.
