Is there gang violence in Karachi at an unprecedented level than seen during last decade? He stopped his empire in India and build it in Pakistan. If you are unwilling to acknowledge the drawbacks of letting a criminal build his criminal empire then I won't bother explaining it to you. I don't want my posts getting deleted for "flaming" when I put across uncomfortable opinion.
The gang violence has nothing to do with Dawood. The issue is not of drawbacks(which you in your blind hatred did not even read that I had acknowledged) but rather of whether Dawood has caused the damage you claim.
Instead, Dawood has used Pakistan to make his rather large amount of black money white.. he rumoured to be VERY legal in his business here. No criminal activity, straight forward legal investments.If anything, Dubai and other African states have greater criminal activity for his empire than Pakistan.
The rest of your post is a feel good rant.
