When these things, these crimes are happening within your locality and worst still, to your loved ones or persons close to you, it does hit differently and leads to fear like you’ve noted, as well as taking decisive decisions that might be for the better or worse.
If it has gotten to this point in some countries (something I haven't really noticed yet in my locality), it's enough reason to be scared.
In addition, you could install security cameras, and advertise the fact that all visitors are recorded on a remote server.
It doesn't change a thing about their operation imo. In a country where transactions on the block chain can't be traced, of what use is a security camera? Just extra bullet holes if they ever find out what your motives are.
Op, get yourself a Glock and get a license for safety.
