Mesa (Az) still as lax about police oversite as it was, like 20 years ago when I lived there? Sounds like it.
When I lived there, I was walking back from Tempe, drunk AF when a Chandler PD cruiser stopped me, on foot. He proceeded to order me to say the alphabet backwards. I pointed out that I'm dyslecix, to which he replied "Then it should be easier for you." I finally hopped up on a wall (They don't have fences in the Valley of the spun, they have cinder blocks) and walked the top of it, 6' off the ground.
To my knowledge, walking drunk isn't illegal anywhere, but i got out of a Public Intoxication ticket by showing off.
