I found the actual paper on the issue much more appropriate in tone than the tech blog linked above. Nowhere it suggests to change laws (the "legal approach" is essentially to get warrants that allow surprise approaches to the targets), nor to regulate encryption.
The meat of the article is simply describing how investigators should be prepared to deal with FDE, when they expect to encounter it, both via legal and technical measures. This alone highly increases their chances of success.
Finally, this reminds me of Matt Blaze's analysis of the 2010 wiretap report, where in the 6 cases where encryption was found, 0 of them actually prevented evidence recovery. I suspect well-prepared law enforcement will be able to be as effective, even in spite of FDE.
