Here's that clip (1 min, 10 seconds) of Bob Drewel talking about public participation being an opportunity for 'Catharsis' - on a task where public participation, the evaluation of tolling, is the primary charge.
Fellow ad-hoc Commissioner Dick Ford sets the stage. FWIW, he interprets Drewel's comments as regarding his, contrary to my interpretation. Ford is very smart and regardless of flaws by association he has made legendary contributions to State Transportation Planning in many commendable ways.
Drewel, in contrast, has, IMO, made a career of being a bureaucratic bully. He was hired to head the PSRC after being booted from the Executive office by the voters of Snohomish County. In my opinion he chose to sell out his County in order to advance his career with the downtown Seattle corporatists. My personal experience with him confirms this, that's another story.
Here's my opinion on the subject.
