Oabama making fun of drone attacks; Families of the dead don't find it funny

Perhaps it may help if you read this:

“Jonas Brothers are here, they’re out there somewhere,” President Obama quipped as he looked out at the packed room.

You’ll never see it coming.”

Now tell us where did he make fun of your dead leaders?
