DALLAS—A distressed and visibly shaken Jason Kidd addressed the Mavericks Tuesday to admit that he no longer felt safe in his own home court after a mysterious figure approached him from behind during the Mavericks' most recent game and took possession of the basketball without his consent. "I don't know if I can go back out there again—it's just too risky," said Kidd, his hoarse voice barely rising above a whisper. "Whoever it was came out of nowhere, and I was unable to protect or secure the basketball before he stole it. I know in my heart that it isn't my fault, but I still feel so...angry and violated." Kidd claimed he has not been this humiliated since an incident in 2001 when police handcuffed him and threw him in the back of a squad car for punching his wife in the face.
