So explain to me why Indira Gandhi was such a prize? From the weblink you cited we read:
>> Gandhi ordered the Army to storm the Golden Temple to remove Bhindranwale and his followers on June 3, 1984. Thousands of innocent Sikh pilgrims were killed in the process, leading to widespread anger over the desecration of Sikhism’s holiest shrine. The disregard for the thousands of civilians within the temple and excessive use of military force has remained a source of great controversy to this day.
Sounds to me like a perfectly good reason for the Sikhs to get upset and bump off a despot.
Unless, of course, you support despots and distrust brave and loyal people who stand up to them.
