As another comment noted, that was Camden. There’s also more to that story - the city significantly stepped up its surveillance of public spaces (https://www.insider.com/inside-camden-new-jerseys-high-tech-...). Personally I think using technology to ensure public safety, with the right safeguards to prevent government abuses, is both acceptable and very possible. However, the anti policing activists are now against the Camden model - they initially held it up as evidence that defunding works but quickly changed opinion when more details came out (that funding simply shifted to the county level). You can find an example of arguments against Camden’s surveillance model at https://jacobinmag.com/2020/07/camden-new-jersey-police-refo...
