Regarding "School knifing and guns" [Letters, April 13], two readers said that a Pittsburgh-area stabbing spree demonstrates that gun control is unnecessary, because determined people will always find a way to do harm.
It's a shame that this has to actually be pointed out: Knives have a multitude of uses. Most are benign. Guns, particularly assault rifles, have only one use: to kill as many people as possible in the shortest amount of time.
If the 16-year-old stabber had an assault rifle, chances are these would have been all fatalities, not wounded kids.
