Not showing your permits - I mean how would they enforce it - will the ranger escort you off the mountain at gun point? Will she call for backup and physically carry you off the mountain?
If someone decided to be truly belligerent - there's not much they can do about it?
For example, when she made me empty out my whole pack just to present the empty WAG bag, what if I hadn't found it? I would've been penalised for being a weary hiker on his way down after a very difficult (for me) hike.
It's not a fit for purpose system.
