Good news! This was shot down last night by the Sun Prairie city council.
Less good news, it was largely for procedural reasons.
Right now, we only have 7 of 8 alders because one of the alders was elected as mayor. One alder wasn't present last night.
The police were requesting a budget amendment to pay for the new cameras. Budget amendments require six Yea votes to pass, regardless of how many alders are actually present (as long as there's quorum, anyway).
With six alders present, only two voted against the budget amendment, which was obviously enough to stop the expansion for now, but it likely means that it'll get funded during the next budget cycle and there's probably not a desire by the majority of the council to remove the existing cameras.
