In the present shoot-out case also, the unfortunate Indian Srinivas Kuchibhotla was not the target of the accused. He died due to the ignorance of the murderer.
Caution: Explosive. Handle with care.
US is a great democracy and it can not lock or seal it's door to highly qualified and able persons from India.
Yes, it is very correct for US to stop entry of terrorists as well as people associated with them but at the same time just stopping every one is not going to help US in any way.
Knowledge is power.
This was not an attack where a group of people converged together and plotted against a people. Taking a human life is not easy and this was a sporadic incident where the perpetrator could not even properly identify the people he targeted.
Humanity is not dead yet because people present there had reportedly thrown the man out when he hurled a volley of verbal abuse on the Indians who were regulars at the bar. There had been an argument of sorts before the shooting. Also, note that a white man got shot when grappling for the gun from the shooter. He said, he couldn't just stand there, he had to do something. It is not all as sordid as it looks.
