They teach you what you already know............They tell you to drive with windows shut,to stay calm in case of a hijack,do not resist,be nice (You have never been nasty until now)......blah,blah,blah........It would be relevant if they taught how to dodge bullets and negotiate with guns (Not gangsters).....The other stuff is about dodging a cow which is shitting in the middle of the road.......Hit it and put it in the boot.You don't need someone to tell you that for a fee.
Yombo dhier....!!
Nothing great was ever achieved without enthusiasm.
