@elefantine97 They do have a lot of time for stuff like these. Specially when one of their core members messes up or if there are drugs involved.
Which is why laws against yakuza have gotten stricter over time. Remember when the gumis had an open gun fight in the 90's, or when they killed an entire civilian family in 2011 and covered it up?
However, now their main source of income is the porn industry, casinos and real state, so who knows.
