don't want to speculate but want to answer a few things--
in a hung jury the state has the option to retry the criminal case. its expensive and rare. what i have seen after hung juries are no contest or Alfred pleas ("look i'm not saying i'm guilty i'm saying you have enough evidence to convict me") on an amended lesser included offense, with a time served component. its just as likely the gov could drop it entirely on may 13 and move on to the next fight.
a civil case is for monetary damages, you don't go to jail if you can't pay. we don't have debters prison in america. the action is not not brought by the state its brought by the injured party. damages would include past present and future medical treatment, as well as lost earning capacity. its a lower standard than criminal (beyond a reasonable doubt v. preponderance of the evidence). However, you cant bleed a stone. Could they win a huge monetary victory against Mr. Vieria -- absolutely. but it would only be empiric. the lien on Mr. Jensen's medical care is most likely well over any thing jessie has in liquid or any assets he presently owns. it really wouldnt make sense unless it was for revenge and most civil attorneys don't take revenge cases.
ill happily answer general questions.
What do you think about the "self defense against a security guard?" "Defending yourself while trespassing against security" ? That's what Vieira's lawyer was telling the press so I'd assume that was the main argument in court.
Couple things I thought about: The picture with Jensen out of surgery, his eyes, nose, and mouth don't look bruised or swollen, so maybe he wasn't even hit by the skaters, or was softly hit and it didn't bruise...thus the argument his injury was caused by the fall and not the skaters?
The other thing is didn't Love Park or other plazas have undercover cops posing as people or security etc? You could maybe see that in the streets. Cops going undercover as security, maybe.
