I listened real close to what they said on the t&v when they expanded on that story, and it doesn't look like the run-of-the-mill suit of the sort we've all become used to...apparently, the suit is over failure to follow the law pertaining to firearms transfers, rather than producing or selling a properly designed and produced weapon that kills people. This one seems to involve the ATF much more than the others, as well.
This might be good for us; at least it stresses the laws that get passed and are not obeyed or enforced. Time will tell.
