You could argue that at some point the "security" is the main threat against your security. It is like if I had some armed guard at a post outside my front door. The risk of him shooting me, or my drunk kids crawling through the bushes to avoid discovery, by mistake or at will due to some dispute surely out weight him protecting me from a 1/100 000 risk or what ever of lethal home invasion.
