To be fair, the Wikipedia pages on law that I've read are quite good (IANAL, just interested), probably because they rarely touch on politics.
Or, perhaps it's that those editors who distort other areas of the wiki to fit their political biases aren't interested in law. It could be either or both (or neither, but I'm biased towards myself;)
From the usual IANAL crowd: "I saw it on the internet, so it must be true."
And if you're an actual lawyer, internet rules dictate that anything you know is trumped by a Wikipedia link.
