You mean the latest racist stabbing attack? The one driven, as usual, by the president's racist words, tweets, and actions? Yes, it is being talked about. More would have died if he had a gun, and thank God he didn't have one, because the racist hate was there.
Democrats are less concerned about the murder of thousands of people every year in big Democrat cities than they are in running Trump and non-Democrats out of Washington.
Democrats enjoy the full faith and support of their stooge media, and together they can blast 24/7 coverage of incidents like ElPaso and Dayton, while ignoring the the daily murder of dozens and dozens in Democrat political strongholds like California, Detroit, Baltimore, Chicago, etc., etc.
Neither Black lives norHispanic lives seem to really matter to Democrats. What matters to them is political power. And that's what we call the swamp.
The way the sequence works isn't from guns to knives but from guns to Improvised Explosive Devices. A 50 pound sack of common fertilizer is far more lethal than knives and assault rifles combined.
One reason why explosives have become the weapon of choice of middle-east terrorist is because its cheaper and easier to acquire than firearms. Surprise: firearms are either illegal or strictly controlled in most middle-east countries. Explosives are available from your nearest garden store, have multiple delivery methods and require very little training, even when delivered via suicide bombers. If no volunteers, they just strap it to a kid.
Also, IEDs are easier for cowards. Remember, OKC bomber Tim Mcviegh was apprehended by chance. Had it not been for a highway patrolman noting his auto had no license plate he may have escaped and done it again, and again.
