joerng, . . . this is certainly not to belittle IZinterrogator's comments, . . . but if it were I: I would go farther back on the basics.
Home protection first begins with the features of the home itself that lend themselves to that protection: locks, doors, and windows would be my first volume.
I am not a professional locksmith, but I have worked the trade, and I am just usually apalled at the locks I find on people's houses & businesses. If I were a burglar, . . . I know enough to generally just look at a dead bolt and know how long it will take me to get through it and/or the knob lock.
Many times, the doors themselves are a joke, . . . as well as the window security (not to mention sliding doors, . . . or their French door replacements). A true oxymoronic joke plyed on an unknowing population is the preponerance today of main entry doors with 300 to 400 dollars worth of hardware in a deadbolt and locking knob. The doors are great, but they sit them inside two 12 in wide pieces of glass called side lights that can be stripped in 15 seconds flat or just busted and reach in and open the door.
Get in a volume about alerting devices, another on motion sensors & lights, in short, . . . prepare the house to make it hard for the bg (that makes it easy to defend/protect).
Once you have given the audience this information, . . . you can then move on to alarms, security systems, etc. But I would seriously put the firearm section toward the rear. You will offend a certain segment of our population just by having it included, . . . but most will look at the rest of the information if they don't have to read about the guns first.
By your writing, prove that you are knowledgeable, rational, honest, well documented, well researched, etc. by giving your readers names (Russwin and Schlage are excellent names in locks for example). Explain why they should have only one key to get into the house for all the family members (as opposed to a separate front door, side door, garage door, basement door, etc.). Build a trust bridge between you and your reader, and you will do well.
You may even be able to convert a reader or two from a position of "call the cops and let em do it" to a position of "its my house, I'm defending it while the cops are coming".
Best wishes,
May God bless,
