No it isn't Raoul.
On 9/11 almost 3,000 people were killed by people using box knives. Not a single gun was used. This is about sorry demented individuals who are too cowardly to just take their own worthless lives. They know that if they just ended their own failure of a life, they wouldn't be missed at all. It probably wouldn't even be reported in their local news paper. This is a selfish attempt at getting attention. A homicidal temper tantrum.
