I mean okay I know I shouldn't be making light of this but the kid pulled his pants down in a town called SURPRISE. Even as someone with a last name that lends itself to bad jokes (and a life-long friend with the last name "Surprise" who similarly suffered), that's just too perfect. Man, Arizona is awful.
In all seriousness, this is pretty messed up. Kids do stupid stuff like pull their pants down all the time, and while I'm glad our culture is becoming more aware of issues falling under the general umbrella of "sexual misconduct," this is pretty clearly a kid pulling his pants down because he's five years old and it's funny 'cause they're pants and the poor kid doesn't have a firm grasp yet on acceptable societal standards*. But that does not a sex offender make.
Also in the future, if the situation ever arises, I would advise that you not do what I just did, which was Google Image search for "funny pictures of little kids with their pants down" in order to find a thumbnail image for this post. Because if I wasn't already being watched by some acronym'd government organization, now I definitely am.
*And I hope he never does. Keep fighting the power, little dude. Pants are the oppressor.
