Brauti made much of the fact that Fenton took over an operational command in "panic mode" following a spate of unprecedented vandalism by "roving packs of hooligans" that transformed the downtown into a war zone.
Under orders from his superiors to take back the streets, Fenton issued his sweeping arrest orders on the fly in an effort to ensure public safety, and his supervisors did not object, the tribunal heard.
"Fenton was not a lone wolf in dealing with this situation," Brauti told retired justice John Hamilton.
"It was not the failings of one man, but rather the failings of an entire senior command."
The lawyer noted that Fenton's prosecution came at the direction of an independent watchdog, not his superiors -- in particular former chief and current Liberal MP Bill Blair -- who later thanked him for his G20 efforts.
Brauti accused the complainants' lawyers of being over-zealous in their single-minded push of a "professional death sentence" for Fenton by turning mitigating factors, such as his exemplary record, into aggravating factors.
"Supt. Fenton has become the focus of the failings in the G20," Brauti said.
That is not about avoiding responsibility -- Fenton apologized after his guilty finding for his mistakes -- but an indication of the context in which he made difficult, if flawed, decisions, Brauti said.
Hamilton will sentence Fenton on June 15.
