As much as I would love to see Nick getting a nickel for his bullshit, I'm afraid I'm going to have to be "that guy." People keep saying he is "fucked" meaning he is going to jail. No, he isn't going to jail. Not now, not ever. He'll peacock and rattle his saber for a while and when he realizes they aren't going to back down, he will ask for a deal and he will get it. He'll get something like probation, community service, and counseling. He'll fuck up at least two of them, but the state won't do jack shit about it because he is an upper middleclass white man and they can't be asked to pretend that they care beyond the initial slap to the wrist.
Maybe if he later assaults a cop he might see a jail cell. The feds take that kind of shit personally. Note that of all the crimes Ralph committed, the only one he ever did time for was assaulting an officer. Even then it's not a guarantee. Tomlinson took a swing at a cop on camera and wasn't even arrested. It's a crapshoot to be sure.
Quote me on it, give me top hats, but I believe I am right. Most lolcows have the Devil's own luck when it comes to legal issues. Nick isn't going to jail, however much he deserves it.
