Sounds like mission creep and overreach to me. Why would ICE be involved in a drug operation that took place in the US and involved smuggling into a foreign country? Unless ICE is now responsible for guns entering Mexico. In any event, I still don't see how ICE could be responsible for ATF's losing track of weapons its agents sold in the US to Mexican gun smugglers.

I think it weakens the argument against DHS to blame them for this, which at best they have an extremely tenuous connection to. Personally, I think DHS should be disbanded. And there's plenty of things it is responsible for that it should be blamed for. Off the top of my head: FEMA trailers, erroneously seizing over 10,000 domains and posting accusations that the small business owners of the domains possessed child porn, TSA, laptop seizures at the border, unconstitutional CBP checkpoints, and on and on.... It just dilutes the argument to add on ATF failures on top of DHS's many egregious failings.
