Oh, yes, a relatively young, very serious and businessman looking person in conservative but stylish clothes, with a stoic expression, standing near some playground, not really doing anything much but seemingly staring into emptiness, busy delving into his own thoughts. That's the prime example of a Japanese sexual predator. Right. The cop would have come, exchanged a few word with Utsumi, both would have bowed 90 degrees full 20 times, apologising their very existence up to three generations. Then both would have left. The perfect waste of everybody's time and the Karenous housewives would have been so proud of themselves.
