You've got about the same odds of viewing that video as you do encrypted satellite broadcasts these days. Why, I'm not sure. If these cameras are really all out in public space, what difference if you're standing on the streetcorner in person or viewing the scene from elsewhere. That, of course, was the non-privacy justification for installing them to begin with.
Of some interest - from the DPD Operations Manual, HALO section:
"The H.A.L.O. Program, with the approval of the Chief of Police, may partner with other public and private institutions and entities in the sharing of camera images with the Denver Police Department. For example, the Program currently is allowed access to cameras owned and operated by the Regional Transportation District, Denver Public Schools, Colorado Department of Transportation and Denver Department of Public Works Traffic Operations. The monitoring of privately owned cameras on the H.A.L.O. network will only occur under a written agreement between the City and the private owner. The Denver Police will not allow access to the H.A.L.O. network to any non governmental agency nor to any governmental agency that is not directly involved in providing public safety services in the City of Denver. Access to the H.A.L.O network must be requested in writing and approved by the Chief of Police"
