I keep a baseball bat by the bed and a shotgun in the corner. That's my plan on resolving a burglary. Somewhere in there it would be nice to call the police. But they are a good 15-20 minutes away and would only be coming to see if I made it out alive or not.
It depends on the specifics. Based on the original comment, if they've already broken into the house, they will be able to break into any room you are hiding in. If they are truly there to beat you to death, you have to be ready to defend yourself with whatever force is necessary to stop that threat. What that level of force is will vary greatly depending on situation, locale, persons involved, etc.
For people not institutionalized with a jailer or nurse in close proximity there is no "external help" that has a useful SLA if you unexpectedly find yourself in a situation where bodily harm is imminent. You either need to prevent the situation from happening yourself or deal with it yourself.
Pretty sure police and most government services don't even give you an SLA (loved that you used that term though, gave me a nice chuckle). It's more of a "we'll get to it when we can". Not to mention, the courts have held that the police have no obligation to protect you (ie you can't sue them for not getting there in time or not rushing into a building to save you, etc).
uhh. if someone is in your house with intent to harm you, the police will not arrive in time to prevent it. Police response times are measured in minutes. You're much better off running away or defending yourself with a weapon, the ultimate equalizer being a firearm.
