Its been a thing of concern when watching presidents from other countries especially Obama while making any speech stand free on their own,with dis strong note of security around him bt nt really behind him, this things makes me pounder towards my own country, y do security officials stand behind our presidents while making any speech? Is this act really an act of security?, can the guy behind him stop any straight bullet from piercing through his fore head, unlike the USA n other countries when their president comes out to make any speech security measures has been taken already to dictate any red pointing towards the part of the president. So I ask if d security official that stands behind the president(goodluck E jonathan) really of importance?.
