Hm. Most of the laws strike me as "very old" and for me it seems as if a general overhaul might be much-needed.
I am not sure a lockdown is the best way, but perhaps there can be some good from this already done situation:
> Admins quickly go through the laws
> Admins PM faction leaders about things that are not cool, outdated, need to be changed, should be discussed, etc...
> Admins unlock it again after the "status quo evaluation", so that all can fix/update/etc.
In general, I do not think that law changes should require Admin permission (as very few actually would go to the length and use their laws in an abusive way). But some checks at some point can also not do too much harm and perhaps correct the few instances in which something went wrong.
