NASHVILLE, Tenn. » Defense attorneys for the former Vanderbilt University football players whose own cellphones show they participated in a dorm-room sex assault have placed blame on the elite Southern university, saying their clients’ judgment was warped by a campus culture where drunken sex was common.

The graphic evidence and testimony presented in court shows that several others were at least partly aware that an unconscious woman was being taken advantage of or had enough evidence to show that something had happened to her, and did nothing to help her or report it.

The bystanders’ failure to act falls well short of the university culture Vanderbilt officials say they were trying to create on campus long before the morning of June 23, 2013.

Closing arguments are expected on Monday.
