They already tried, with the Clipper chip. It was clearly a very bad idea, and flawed, but that won't stop more attempts (and with software, the costs are much more hidden, and the flaws are probably more hidden as well). It's quite possible for legislation involving key escrow/recovery, import controls and mandatory sentencing for using noncompliant crypto and so forth to pass the current senate and house, regardless of the technical shortcomings of the solution. My belief is that the LEAs are waiting for a sufficiently egregious event involving crypto so they can push through legislation rather than attempt shaky arguments in court with the current laws. Guessing that the phone involved in the recent shooting was unlockable, at least initially, and didn't contain anything sufficiently interesting to make political hay out of.
