Hearing about some of the violent home invasions and the types of folks doing it, not sure anything is too powerful.
Here's the best advice I can offer you: turn off the evening news.
Among the things that you won't learn on the evening news are these: the violent crime rate in the US has dropped by a third in the last 15-20 years, and the US is safer today than it's been in close to 50 years.
They won't tell you that the number of "hot" burglaries in the US is very low, specifically because burglars don't want to get their brains splattered all over the walls. Your house is ten times more at risk when you're not there than when you are.
They won't tell you that the number of people who break into houses while high on drugs is extremely low, or the fact that being loaded to the gills doesn't make someone bulletproof. A guy on crystal meth who's shot with 2 3/4 inch buckshot will drop dead just the same as a guy who's not on crystal meth.
What the evening news WILL do is scare the s--t out of you, because scared people stay tuned to find out the latest. If they're not keeping you in a state of suspended terror worrying about what you don't know and they might be able to tell you, then they're not getting as much money for their commercials. It sounds pretty horrible to say, and it is. But scaring people is big business.
