Looking at the Han River Bus allegations, a full-scale investigation into corruption in Seoul's redevelopment projects is also necessary.

Redevelopment is where the most corruption breaks out, and there are far too many cases where union chairmen are punished.
In an area where there is so much corruption, there is no guarantee that the district and city offices were not involved.
The kickbacks involved are enormous.
Therefore, reconstruction and redevelopment projects must be investigated even more aggressively than the Han River Bus project.
A massive number of reconstruction and redevelopment projects are underway, and there is no guarantee that rebates are not occurring there as well.
Redevelopment is a much larger-scale operation occurring in many more places than the Han River Bus.
I hope they conduct a thorough investigation of everything and use this opportunity to clean up the system.
