Jacob White

Jacob White is a character in Deus Ex: Human Revolution. He is a member of Motor City Bangers gang, involved in the Smash the State sidequest.

Background
He is a MCB member that has become increasingly violent and unstable, as reported to officer Nicholas by a street informant. White always had a grudge against DCPD, and with the augmentation riots erupting worldwide, he decided to partake in his own way, planting a bomb underneath the local police station.

The bomb had indeed been planted there, and is guarded by White himself, alongside several mines and turrets, but turns out to be gas ordinance, rather than explosive. The bomb can be defused in a number of ways. You can hack it, guess the code (it is 0000) to recieve the Lucky Guess achievement, or you can, rather oddly, defuse it by using a gas grenade.
