This from TNT Husky beat reporter Todd Milles:

As a way to recognize Sunday's killing of four Lakewood police officers, the Huskies are offering four free tickets to Saturday's Cal game to all active police, military and fire department personnel. 

They can walk up to the ticket window on the northeast plaza Husky Stadium on game day to receive the tickets, or call the UW ticket office (206-543-2200) ahead of time.
