Apparently this uncle who professed to be a Akido teacher, was upset at a bunch of unruly youths for not parking their bikes properly and making a ruckus late in the evening.
So he went back to change into his Akido garb armed with a wooden sword to want to "teach" these youths a lesson.
What ended up as most would have expect was that this uncle got beaten to a pulp.
So much for being an Akido teacher.
