if its not illegal to use a phone then the kid should have kept his nose out of other peoples business. he did it to himself, if there was a law about not using the phone then I would say the officer over reacted to a concerned citizen, after all, if I saw a driver necking a bottle of vodka whilst driving I would do whatever I could to prevent that person hurting himself or worse someone else, if it turned out to be a police offer then so be it. Breaking the law is breaking the law, regardless of how or why, kids an idiot tho, even if it was illegal, you have to accept that it might have been police business and STFU
