Earl Smithies

Earl "Dog" Smithies was a plastic explosives supplier.

Trinity
Jack Bauer and Harry Driscoll found Smithies through Mark Gelson, who paid the former to blow up some plastic explosives and "raise a little hell". Jack went to see him at the Killabrew bar. Jack stirred Smithies interest by pretending to want some bombs. However, Smithies knocked Jack out, realizing that it was unusual to just start talking about bombs as he did.

Smithies tried to get Jack to admit that it was Andre Farrigan who set him up, but he was killed by a team of LAPD officers before he could ask many questions.
