"City attorney Bill Falsey said Tuesday that Anchorage police are unable to provide services past McHugh Creek".  My understanding is that DPS decided decades ago that all law enforcement officers are certified by the state, so therefore jurisdictions are irrelevant.  Remember the (TS)AIA cop who chased the kid all the way from the airport to Indian and killed him?  I'm sure that line at McHugh Creek really won't matter to APD if push comes to shove.
