'Prey' for the city

They're reunited -- and it must feel so bad for the petty thugs, the bad apple cops, the shysters and all others who now may get sucked into the journalistic polar vortex that is Barbara Laker and Wendy Ruderman. The dynamic duo mark their return to Daily News action today with another Pulitzer-worthy package -- this time talking on cash-grabbing lowlifes who prey on the city's infirm and its mentally challenged.

If you want to find out about how these two amazing journalists do their magic, come this Monday night to the Prince Music Theater in Center City for a screening of "Black & White and Dead All Over," a documentary about killer whales newspapers -- they'll be leading a panel discussion afterwards. Then, pre-order their coming-in-March blockbuster book Busted, which tells the improbable story of how they exposed crooked cops and won that Pulitzer,
