I agree that he is unrepentant about his banning behaviour. I am just not convinced those crimes deserve jail time. It's mostly loitering and causing a nuisance.
I just don't see what would be gained from jail. He seems scared of it. Enough that he learned his lesson about pepper-spraying. And sending him to jail is not going to make him have some great epiphany. It will just reinforce the "no pepperspray" point, which seems to have sunk in anyway. And it would be really miserable for him.
If he was going around saying "fuck that gamestop guy, I'll mace whoever I want" I would agree that he needed to be smacked down by some jail time. But as it is, I don't want him to go to jail. It won't help him, but it will make him miserable.
I am in the minority though. I don't think there is anything wrong with hoping he gets a month or two. If you think he deserves years in prison you should probably check yourself, but I do see the perspective of people who think he deserves a short sentence.
