Meh, so long as they got it for cheap/free, I'm ok with that. (Speaking specifically to the Wright County one, as I live in Wright)
Shit does happen and it's better to have it and never need it than need it and not have it. The odds of it ever collecting more than a paint scratch are pretty slim, and that's ok. I expect most of it's use will be as a part of a DARE program, or in parades.
I'd by hyper-annoyed if they actually had to pay money for it, but they didn't...and outside of St. Michael, Albertville, and Monticello the county is about as quiet as they come, IMO.
All it takes is one group of assholes to decide to make a point with blood to justify this shit these days...at least our county Sheriff is a 2nd supporter and probably knows an armed populace is the best backstop against crap like that happening.
