Unstable Neighbor Threatened to Shoot Me and Police never showed up

Theres a drunk at my apartment(west seattle) that hangs out on his porch screaming at people and starting fights. This has been going on for months with threats of violence and screaming obscenities in the middle of the night. Called SPD several times and they never show up. He threatened to kill me today and its been three hours still no police. WTF is going on in Seattle, is our police force even functioning anymore?
