DNA: Parliament Security Breach Update: No lesson even after 22 years of Parliament attack?

Today is December 13th, the 22th anniversary of the terrorist attack on Parliament. Many of you may not even remember this attack. However, today something happened in the Parliament building that reminded everyone of the attack that took place twenty years ago. Around 1:15 PM, Lok Sabha session was going on. BJP MP from West Bengal, Shwetang Murmu, was delivering a speech. Suddenly, a noise was heard from the Visitor's Gallery. Members of Parliament thought that someone might have fallen from the gallery. However, a young man started jumping from one bench to another. After that, there was chaos among the MPs.
