"There are a few things we need to keep in mind," Mayor Nutter said. "He's running for re-election, and to the extent that he thinks that being a doomsday crier protects himself from citizens who may be upset by their assessments and a possible increase in their taxes, he may assume these comments are in his interest."
When asked about his comments, Butkovitz initially said he couldn't recall what he had said, noting it was a two-hour meeting and there was "a lot of give and take."
"I probably said some people will be forced out of their neighborhoods," he said.
Butkovitz provided a 20-minute recording of his the first part of his presentation, which he said explained his analysis of the assessments' flaws. On the recording, Butkovitz discusses potential tax bills with a 1.5 percent tax rate. Nutter has proposed a 1.32 percent rate.
"The whole assessment was sold on the idea that assessments were unfair in the city," he said on the recording. "Looks like the errors are worse under this new assessment than they were before."
He said residents should team with the Crosstown Coalition of Taxpayers, which may file a class-action lawsuit. They have money, he said, and "they have the same idea as you. They want to throw this out."
Butkovitz disagrees that he was stirring fear over AVI.
"There seems to be some argument out there that I don't have the right to help people understand this or advocate for protections."
