So good because it's so natural. Just what kids do. This kind of picture involving the innocence of kids and their amusing behaviour was in every kind of "HowTo" photography book just a few years ago.
How have we allowed ourselves to sleep walk into an irrational culture of fear, wholely disproportional to the situation, where anyone taking street photography is in danger and anyone whose shots involve kids in any context is in serious physical danger and assumed guilty by the authorities until proved innocent?
If only we could galvanise Joe Public to react the same way when there was even a hint of a mugging and where the fear is often wholely rational then we'd all be a lot safer.
Soon all such prints will be last century, if they aren't already.
