Ebert skeinir sig eina ferðina enn uppá bak

Robert Ebert says he "was probably too quick to tweet" about the car crash that killed "Jackass" star Ryan Dunn yesterday ... explaining that his post was "not intended as cruel."

Ebert just blogged about the situation on his website -- saying, "To begin with, I offer my sympathy to Ryan Dunn's family and friends, and to those of Zachary Hartwell, who also died in the crash. I mean that sincerely. It is tragic to lose a loved one."

Ebert continues, "I also regret that my tweet about the event was considered cruel. It was not intended as cruel. It was intended as true."

Ebert explains that he wrote the tweet based on preliminary reports and admits, "I have no way of knowing if Ryan Dunn was drunk at the time of his death."
