Giuliani has an incredible record aligning with corrupt operatives that he places in power positions.
His "crime fighting" record is great if you like living under an authoritarian who won't hesitate to seize your property or frisk you in public, all in the name of "security." Freedom? Oh, that's not important...
"Freedom is about authority. Freedom is about the willingness of every
single human being to cede to lawful authority a great deal of discretion
about what you do and how you do it."-- Rudy Giuliani, New York Times, March 17, 1994
Besides that being a left wing position, I can tell you that I've met with top police commanders who implemented the NYC crime crackdown, and they were extremely careful to proceed in a lawful way that was approved even by New York's liberal judicial system.
