On Monday morning, April 18, 2018, an 8 year-old boy left home with a kitchen knife and walked into his central Minnesota elementary school. Minutes later, he slashed three fellow pupils, ages 8, 9 and 13 years.
It was an example of how once again, a perpetrator doesn't need intense knife training to cause damage to others, and homeland security professionals or enforcement agents must accept that anyone carrying a knife represents a real danger, even if he/she appears that they don't have a clue as to what they are doing.
