I live is SA too i know what we get here , maybe you forgot that. Your opinion like many others is your opinion that does not necessarily mean its base on fact. In my personal experience dealing with home invaders.
They shoot fucking well.
They carry something better than a spare mag, a buddy with a fully loaded pistol.
Just because there are the “unprofessional shaky nervous” whatever you want to call it. Murphy law you will get the guys that experienced.
Also when there only escape is to get through you…..you bet your ass they are staying to shoot it out with you.
Plan for the worst and all that.
