Yes this is very true. Claiming that Bergwall (=Quick) was guilty was a win-win-win-win situation

- Bergwall got the drugs and the attention he craved - His lawyer got to represent the worst criminal in modern Swedish history - The doctors that were close to him at the hospital could make themselves names in the academic community in how successful they were in their methods of "retrieving" the hidden memories of Bergwall. - The lead police investigator got attention and recognition - The same with the prosecutor and so on.

Few (or none) in the system had incentives to pull in the opposite direction.
