hey pacific, is there an age for the kid, because i think that could make a world of difference (between a 5 year old shooting and an 11 year old). The brightline test that law123 puts forth is a viable answer, but other jurisdictions will determine if his actions were that of a reasonable child of like age. I am a bit suspect on the battery issue because since we dont know the age we cannot determine if he "knowledge with substantial certainty" that injury would follow. Sure the kid could have intended to hit the balloon, but did he know the repercussions? If this came from your exam and the age was intentionally left out, it is my guess that your professor wanted you to analyze both a young kid and a not so young kid or that's how i would have done it (assuming i would have had enough time, which is like crack during exams, you can never get enough of it).
