Why Mindfulness is so important today?

Early this week a grandfather in Australia killed all in his family including himself. He was till then considered a nice person by neighbours. Just late last month a boy walked into his former school in Florida USA and killed 17 students and teachers. Just two days ago a boy in Texas walked into his school and killed 10 including two teachers. All over the world people are blaming firearms. But the truth is firearms cannot kill unless they in the hands of the wrong person/s. In all these three cases immersed hate caused mental stress leading to them doing the extreme thing, kill others. So the solution to the problem is not arming the teachers with guns as one official in Texas said today, but building mindfulness in all. That can come only with Mindfulness Meditation followed by Vipassana. When will the governments world over wake up to this reality?
