Just quickly googled this case, seems there were no witnesses and no actual physical evidence to link the guy to the shooting, so maybe not proved beyond reasonable doubt? despite being against guns if a drunk driver wiped out my family he'd have to be glad I didn't have one in my hand.
Do you mean she's never learnt - keeps trying and falling off or never learnt - never been on a bike?
I was in my twenties when I got my first bike and learnt to ride it. Ten minutes in an empty car park, saddle low enough to put my feet down. If she's tried scooting etc and is still struggling there are some very elegant ladies tricycles out there.
