R. Kelly's attorney guided his electric scooter down a hallway outside the courtroom where his client is on trial for child pornography, exclaiming as he sped past several reporters, "In the morning, we attack!"That battle cry last week from Ed Genson, who suffers from a neurological disorder that makes it difficult for him to walk, was apt: After two weeks of prosecution testimony, the R&B star's lawyers have a lot of ground to regain.After launching their defense days ago, Kelly's lawyers are endeavoring to breathe life back into several key claims when the case continues this week, including that a mole on Kelly's back proves his innocence and that a sex tape at the heart of the case could have been doctored, possibly as part of an extortion plot.
