Walt gave police a confession on the phone.
You think he was going to jail based on that phone call? She was the only living witness on Walt they had whereabouts on. Hank, Jesse and Gomez, missing presumed dead. Saul gone. Tape of Jesse gone. They don't know about Jack and Meth Damon. Why do you think they were leaning so hard on her?They didn't need her to convict Walt, so why would she be in protective custody?
What would killing her accomplish? They had enough info on him to RICO his house and car wash, without Skyler saying one word. The only reason the DEA was talking to her in "Granite State" was to ask where he was, not "give us enough to convict him". They had enough already.

Ignoring her importance to the case. The last time Walt was in town he attacked her with knife, kidnapped his daughter and threatened to kill Sklyar. You don't think that warrants more than one unmarked car half paying attention to them.
Tell that to the cops/da from the OJ trial or the ct cops investigating A-Hern.They had enough already.
DEA- "Forget about security for this living witness who's a potential target of our suspect. We have Heisenberg on the phone alluding to some indeterminate illegal activity he was into. That's enough for me."
Come on breh, the show is still great and I didn't even mind it when I watched, but that was a pretty glaring plot hole.
