I tried out the game - It is quite clever and well thought-out riddle.

If the policeman is a kid too (certainly looks like that), then the solution would be that mom crosses the thief (which looks like a girl to me) first (thief is then alone, and causes no trouble), then dad crosses the policeman (policeman guards thief, so there will be no trouble), after that, each of the parents can simply cross any of the kids of their own gender. ) On the last pass, mom and dad cross together.

The other alternative would be to turn it around completely, crossing the thief last, and the policeman right before that.

But I must admit I didn't play the game at all... Think I'll try that now...

(EDIT: the policeman is an adult, as the question states... dumb me! This all goes down the drain!)

(2nd EDIT, after playing the game) Man, is my solution flawed... It can be done, but it's easy to make mistakes with this one if you're not careful...
