Killer whale attack updates

We've all heard of the unfortunate incident at SeaWorld, Orlando, in which trainer Dawn Brancheau was attacked and drowned by the killer whale Tilikum. Tilikum has supposedly caused two other people's deaths in the past, but a former head trainer at SeaWorld (and good friend of the deceased) told "Good Morning America" this morning that Brancheau was to blame. Thad Lacinak said Brancheau allowed her ponytail to drift into Tilikum's tank, which spurred the whale to grab onto the hair and drag her into the water until she drowned.

This is what others are saying on Twitter:

Despite the recent events and events in the past, SeaWorld has decided to keep Tilikum in captivity and in their killer whale show. Good idea?
