I've never heard of a Police Department closing down at night. What happens if someone needs an ambulance in the middle of the night? Is there a Fire Department that responds to night calls? Will a call to 911 at 2 AM be get a response at 7 AM? The mind boggles.
Although officially, the police where we last lived were open 24 hours as is legally required, the truth was quite the contrary. We found this out the hard way: being woken up at 3am by a crazy homeless guy swearing death threats breaking our windows by smashing them with a knife. The police did not pick up the first few times I called. When they finally did, the guy took down my details, said he'd send someone ASAP, and nothing came of it. DH also called separately and had a similar result. No-one ever came. We kept calling, and were told (on the few occasions where the phone was answered) that either someone was already on their way, or that someone would be sent immediately.
We later complained to high-ups and higher-ups but since officially the police had no record of our call or the crime we reported, they refused to believe that any incident had occurred. Eventually it became obvious that nothing short of a hundreds-of-thousands-of-dollars lawyer and several years in court would change things. We have since heard similar stories from many, many other people. The people it hasn't happened to generally chalk it up to us exaggerating or lying. The perception of public safety is basically a delusion.
In the same area, it was well known by all the locals that if you call an ambulance, you needed to mention heart problems (even if they weren't there) because it was the only way to guarantee that the ambulance came within half an hour, or at all.
It is scary to realise that the safety net you always thought was ready to catch you when things fell apart just wasn't there, nothing could be done, and no-one cared.
That reminds me of a joke I heard.
George, an elderly man, was going up to bed, when his wife told him that he'd left the light on in the garden shed, which she could see from the bedroom window. George opened the back door to go turn off the light, but saw that there were people in the shed stealing things.
He phoned the police, who asked "Is someone in your house?" He said "No" but some people are breaking into my garden shed and stealing from me.
Then the police dispatcher said "All patrols are busy. You should lock your doors and an officer will be along when one is available". "Okay" said George.
He hung up the phone and counted to 30. Then he phoned the police again.
"Hello, I just called you a few seconds ago because there were people stealing things from my shed. Well, you don't have to worry about them now because I just shot and killed them both, the dogs are eating them right now" and he hung up.
Within five minutes, six police cars, a SWAT Team, helicopter, two fire trucks, paramedics, and an ambulance showed up at the Phillips' residence, and caught the burglars red-handed.
One of the policemen said to George "I thought you said that you'd shot them!" George said "I thought you said there was nobody available!"
