So, here’s the mugshot from Quinton Jackson‘s arrest on Tuesday, courtesy of TMZ (the Andy Dick booking photo is there just for comparison, I think). The Press-Telegram reports that Jackson’s court date is scheduled for August 15th at Harbor Justice Center in Laguna Niguel, and that he was cooperative with police from the time of his arrest to his release.

Unfortunately, there’s no word yet on why Jackson was shirtless in his mugshot — though one can’t help but see it and think “erratic behavior.” Speaking of which, a source semi-close to Jackson, who asked to remain anonymous, told CagePotato.com the following:

Close friends of Rampage had been very concerned about him the past few days [before the arrest]. He was very depressed and acting increasingly strange. There is something wrong with his mental well-being. They do not believe it is drugs or another substance. I have heard from others who said they’ve been concerned about his mental state for the past year. When he was in custody yesterday his blood pressure was sky high which is why they hospitalized him. Personally, I think he is out of touch with reality.

For now, treat that only as speculation, and pray to your Higher Powers that Rampage pulls out of this. More to come…

UPDATE (9:06 a.m. ET): Rampage may have sideswiped a pregnant woman during his little adventure:

[Holli] Griggs was taken to the hospital for minor injuries, [California Highway Patrol officer Jennifer] Hink said. In an e-mail sent to the Daily Pilot, Griggs said she and her unborn baby, 16 and a half weeks along, were injured but was not sure to what extent.

Griggs said Jackson was acting “violent and reckless” and “had no regard for my life or anyone else’s for that matter.”
