Geezerly. In 76 the city limits were Airport Heights, Tudor Road &  Seward, & Fireweed. Your State Troopers covered the rest from Turnagain Pass to Knik # 1 and included the Air Port, Oceanview, Bayshore all of Hillside, Eagle River, and  Peters Creek,  covering about 80% of the Anchorage population. You saw Troopers every where and most arrests and convictions were made by State officers. One Trooper kept a lid on at Girdwood and patrols from Anchorage AST provided off duty coverage. Politics and politicians changed all that and now foot patrols resume in the core area.

And how much of the State budget was based on oil revenues? Not a lot as the oil had yet to flow.

Maybe better managers would have kept the coverage you had and were entitled to.
