It is obviously bad to have such a devastating incident. My condolence to the family and relatives of Mr Bhattarai.

Just not working in the store does not at help at all, especially for the student. But, we should be educated or help  to educate people how to avoid such thing, if possible. I came after undergrad in Nepal so did not have to work at the store, as I had some other resources from the university too. But, this does not apply for all of us. It would be great if some experienced one could share helpful tips to stay away from shoot out or something like this.

Like, if someone is with the gun or any sort of weapons in the store don't confront. Let her/him take the things he wants, you can report this later to the police or your employees. Being too friendly with these craps (especially African-American) could also lead to a loophole for them to encourage. From the video, it sounds like killer was quite familiar with the store or was well informed about the position of employee. Just a thought.
