telli. philadelphia trained engineers and electricians are heading back to work. president obama intervened in a tran it strike. the emergency board with will now mediate the contract negotiations. more news later right here on msnbc. right now back to "lockup." due to mature subject matter, viewer discretion is advised. we've covered dozens of gang stories on "lockup." but the ones that really stay with us are about the young men who have tremendous potential, that they've squandered away by joining a gang. the story of two brothers in oakland struck us that way. and their story had a deeper impact on our crew and our staff than possibly any story we've ever told. >> gabriel and ezekiel taylor
