The firing of cops who indiscriminately beat three suspects after a car chase, and the passage of local gun restrictions, are controversial, radical - and necessary.
They reinvigorate a civic sense of empowerment after years of frustration.
And they clearly embody what should be Nutter's new slogan:
"Doing nothing is not an option."
The mayor made that comment after signing a new firearms law passed by City Council in defiance of the state prohibition against local gun regulations.
The law would require the reporting of lost and stolen guns, limit purchases to one a month, ban assault weapons and institute other crucial restrictions.
Nutter knew, and so did Council, what a judge said on Monday:
"It's the state that regulates firearms and that's plain as day," said Common Pleas Judge Jane Cutler Greenspan.
The judge almost certainly will uphold the National Rifle Association's challenge to the city law, as she indicated she had no choice but to do.
But the city vowed to appeal.
You can argue that fighting the battle is a waste of city resources, given the clarity of the law.
And I personally don't think Philadelphia-only gun rules make sense, because the two gun shops that are challenging the law along with the NRA can just set up shop in a county next door.
Even some advocates of gun restrictions disapprove of the city's "stunt," arguing that unseating opponents in the Legislature is the only way to accomplish the goal of gun limits.
But I applaud the mayor and Council for the audacious act of civic disobedience.
(I even agree with the NRA lawyer's demand that Nutter be arrested for "official oppression." What a great photo op: a mayor behind bars trying to protect his constituents from gun violence.)
The "stunt" keeps the issue in the public eye, keeps the pressure on state legislators and may even result in new state regulations.
