National, no. But four teens getting stabbed in a single incident might very well be news in most of Texas, which is only about half the population of the entire UK, and well over half the population of England proper.
Four teens getting shot but not killed in gang-related activity would possibly make the eleven o’clock news but probably not make the front page of the large urban papers in Texas, certainly not national news. For a stabbing? No chance.
America's a big place.
