Meh. There are too many details from this missing to really make a fair desician, but really it sounds like the newspaper trying to make a mountain out of a molehill. It's a pretty unusual situation, but I don't think it's worth reacting that strongly about.
At the gist of this case is the spanking she received. In the Seattle Weekly article it does mention that she was basically spanked by her father accross the buttocks and legs with a switch BEFORE the sword fight. There is actually nothing here even suggesting sexual abuse (despite the images that come to a perverted mind) so it seems to be a pretty straightforward case of discapline. This brings up the bigger issue of one's right to inflict corperal punishment on a child, and the bigger issue of when (if ever) a child becomes too old for such a thing to be appropriate. Spanking/switching a willfull teenager who does something like this is HARDLY a unique situation, though increasingly uncommon and it's own topic of debate.
The outlandish aspects of this, those with the two hour swordfight, took place after the spanking, and it's noteworthy that the girl put on the armor and went out to fight him. It's not like she ran away or anything. From the mother's reaction I'd be lead to believe she was pissed about the spanking and said she was going to kick his ass or something and he gave her a chance to do it, in a somewhat controlled enviroment, and in the process made a point.
This guess... and mind you there are details missing, is largely based around the simple fact that the police response is AFTER this had been going on in the FRONT yard for two hours, and at the report of a friend who got a text message. All comments about the detachment of society, and the whole "Kitty Genevieve complex" aside, one would think that if there was something paticularly vicious going on, and this girl was being mauled by a tree branch this probably would have been reported by the neighbors. Rather there is no report about anyone being concerned about this for *TWO HOURS*.
As far as her having bruises, well yeah, that's to be expected after that kind of thing, but as far as being beaten "by a tree branch" that would be more than bruises if she was actually being assaulted/mauled.
I'm not saying this is a normal situation, but I don't think it's that big a deal either. There are issues here, but not the kind of issues I expect to cause any kind of backlash against groups like SCA enthusiasts or whatever.
Who knows if we'll hear anything else about it, but I'm kind of expecting this is one of those cases that is just going to dwindle away, because while the whole "costumed sword fight" aspect of it makes it stick out, it's really not going to be anything paticularly special.
The $10,000 bail is interesting, but at the same time the media did get their mits on this and started screaming it from the rooftops, which means the authorities have to treat the situation as being something paticualrly special due to public imagination, even if it's not. Under any other circumstances I'd think we've never hear about it, and the whole discussion would be about corperal punishment, and what rights parents have to enforce disapline on children who live under their roof. Did this guy go too far? Honestly, I don't like it, but at the same time this is pretty much a "meh" example since the girl was banged up again and has bruises but wasnt exactly hurt. It's not like cases where you have kids being sent to the hospital every other week with concussions and broken bones which are the real horror stories that causes these issues. I can't really bring myself beyond a mild discomfort/dislike at the worst upon reading this... he spanked her with a switch? OMG stop the presses. Personally I'd rather put the morons who do stuff like burn their kids with cigarettes and leave the marks all up and down their arms waaay ahead of the pack before this guy. Comments about gradual cycles of abuse don't seem to apply here since the girl is already 16... and I mean she DID break the rules in a pretty big way. I might not care for the penelty, but beyond that it's EXACTLY the kind of situation where you'd expect it to come into play, it's not like he did it because she spilled his beer or something.
