The room actually got a little warm.
It doesn't surprise me, because there is the existential dilemma between a self-reporting and a self-assessing system, and there is a market economy and competition amongst law firms and accounting firms to attract and to retain clients.
I suppose the point is that if those law firms have broken an ethical law or have contributed to a client being able to commit tax evasion—that in and of itself is a crime, and I would definitely not condone that.
The fact that there is a beauty contest amongst lawyers or multinational accounting firms to provide clients with the most tax-efficient structures doesn't surprise me. That's just a function of the market economy and of competition amongst those firms.
