I'd hate to be that poor 9yo girl. I can't imagine such a small child would present such a risk to a police officer that they'd have to zap em.

I've been tazed like... I dunno... 10-12 times (one of my fraternity brothers had one in college and so for shits and giggles we'd get drunk and taze the hell out of eachother. also, for an old job I had, part of our training involved using them on eachother as well as spraying eachother with mace and pepper spray to "understand what kind of force we were wielding") and lordy lord it's not pleasant. Although more debilitating than actually painful.

Goosebumps are perhaps the longest term effects you'll get from them unless you're unlucky enough to have a heart condition or be chewing on something at the time but regardless, it ain't a whole helluva lotta fun.
