She might be in real trouble on this one. If it comes out that the sheriff or PD was working on the appropriate warrant based on the DVRO and she jumped the gun (heh) to commit burglary, then it's unlikely law enforcement will be lenient. Especially since, from the story, the guy was in jail at the time, so she had time to let the popo do their thing.
Also, she chose to do this in Polk County FL. you can DuckDuckGo Sheriff Grady Judd for anecdotes, but the bottom line is he's unlikely to overlook vigilantism.
