Mt61 I think that's over the top.
Being killed by someone you haven't let into your home in the ordinary way (as a husband or close friend) is such a ridiculously low risk!
If you genuinely think you need to do this - I think that maybe you aren't feeling very well.
Please get some help. 
No, I think it is you is deluded! There is nothing wrong in keeping ourselves safe. Our South African neighbours had only moved in the previous month, when all hell let loose on our cul-de-sac- five luxury cars stolen, including a tourer, police said it was an outfit from Merseyside, (they never shit on their own door steps these burglars), my friends French doors smashed in, luckily her son was home on a visit.
All the neighbors have installed cameras, including the SA neighbors who thought they were in a safe country 🙄- so all must be sick too!
