PSU Students charged in death

[*bfine32*]

Apparently, 18 students are being charged with the death of a fellow student, because he fell down some steps while drunk:

Curious at to folk's thoughts on this.

My initial thoughts:

The guy in the embedded interview in the OP is throwing folks under the bus as fast as he can. "He begged" folks to call 911. Did he not know the number?

What can they be charged with and why?

If they had called 911 as soon as he fell and he still died; should they have been charged?
