You can buy tasers at any market here,keep it in the home,who is to know?
I have lived in the same place here for over 15 years and have never locked a door.
Keys are in the truck always ,the same goes for the bike.
The thing is when people break in they also need to leave again.
Our place is very hard to find even in the daytime.
We have a few dogs,they will let us know when there is something wrong.
No need for weapons here,
I would say the best protection would be a safe room,let them steal a bunch of used stuff
it can all be replaced.
