a to z security / gadgets for vips or citizens needed , ok,

but can  govt think of any radical ways , irrespective of whether innovative/ modern /ancient/ traditional / technological/ theological ,,,which can eliminate the very possibility of occurrence of terror/ violence/ attacks… so that every one lives a safe life …..without the necessity of all the complex/ costly paraphernalia……
tigers/ lions are ferocious animals … but we see a few human beings are livingwith them, safely lovingly as if their pet dogs
