No, it's not nice, and, yes, you can get arrested, but covering the houses in the Denver Country Club/Polo Grounds neighborhoods with toilet paper in post-midnight raids is an age-old tradition in Denver. And for good reason: There are lots of places to hide behind well-trimmed bushes and stone entry gates, there are no major streets with long sight lines for roving eyes, and the professional landscaping, branchy old trees and grand homes afford many excellent ledges that a well-thrown roll of toilet paper can easily latch on to. Best of all, there's no reason to feel sorry for the very wealthy people who live here after you've TP'd their manors; they'll just have their staffs remove the offending paper products in the morning.
