Sources close to Chris tell TMZ ... he will soon have 24 hour security at his home ... with one guard inside and another in a vehicle outside. We're told the guards have their marching orders ... open fire if necessary. According to sources, Chris has taken advice from professionals in his life - as well as his mother - and agreed to significantly limit the number of people he invites to his home.
Chris & the LAPD believe some of his friends were in on the break-in earlier this month.
