Yakuza Encounter

I just got a report today that yakuza(organized gang) has recently been gathering in this area. I hadn't a clue yakuza members lived around here, but now I understand it is well known around town. I saw them last night.

My friend Kara will be leaving Japan in a few days, after three years living and teaching here. So, we decided to meet for dinner at Cafe Miami, near the Tamana train station. She took the main road there, but I took some back roads, since it was near my house. When we arrived, I told her that there was a group of 25 or so men in blue uniforms holding red light wands standing in the road. They moved when I pulled my car through, and I saw on my right, a desk with two shaven-head men in uniforms staring intensely at me through my car window. I felt alarmed and vulnerable for a moment, and then I saw two women dressed in black turn into the alley from the busier street near the restaurant.
I couldn't get a sense for what was going on: I thought it must have been a funeral.

We forgot about it and ate our pasta.

Today's report went like this: A friend of Tamana Girls' School has reported this afternoon that Yakuza gang members have been seen in the area behind the train station. Teachers are asked to stay clear of that area, and tell their students to stay clear. The police have a watch on the building where members have gathered, but as of yet, there is no further news.

I have nothing to do with yakuza, except we live in the same world, under the same universal laws. Their world affects mine and vice versa, to a lesser degree, I'm sure. But are they 'bad,' and the police 'good?' And couldn't one easily become the other, as easily a friend can become an enemy? I feel strange when the connections/interactions between people is broken and people get labeled off-limits or scary. On the other hand, maybe it's always good to stay away from negative influences. Or, as a superhero we could go straight into them without being affected. (Didn't I mention I have a t-shirt that says, "I wish I was supernaturally strong, so I could put right all that is wrong." But it's difficult to wear that shirt outside of Japan because it sounds so presumptuous. The idea is nice though.) The other answer is to get rid of the concepts of right and wrong all together. Which is more difficult?
