It is my belief that the bathroom and the sleeping quarters of any dwelling should be the most secure portion of the house. They should be separated from the rest of the dwelling by a bolted steel door, and any windows should be barred in that portion of the dwelling. There might even need to be firing holes in that diamond 1/4 in double clad steel door. The import point here is that if an attempt is made to break in during the sleeping hours, there is enough time to mount a defense, which would not be available when one is groggy from sleep and surprised. Other protections such as guards or alarm systems might be circumnavigated by the gang, but a defensive sleeping fortress is a worthwhile thought.
