After contemptible army attack in June 1984, the Indian army stormed the Sikhs' holiest shrine, the Durbar Sahib (Golden Temple) in Amritsar, Sri Akal Takhat Sahib other historical Gurdwaras of Punjab, and thus, then Prime Minister Indira Gandhi did the contempt, intentionally and deliberately, of Sikh religion and of killing of thousands innocent Sikhs including minor children and women in the army operation.  

Under the circumstances, the conceited Indira Gandhi proudly wanted to send a message worldwide that after all this, she was not afraid of Sikhs and, to prove further them coward, kept Sikhs her bodyguards in the inner security circle, from where nobody could ever escape and think so to take the risk of committing the crime.  

But, Beant Singh and Satwant Singh took this extreme step because of the outcome of intense feelings that carried away them, for the reasons of the deliberate religious contempt and the killings of innocent Sikhs by her action and the Indian army.   

It would always be wrong and incorrect to say that she trusted Sikhs as her bodyguards.
