We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Arakaki v.

Hawaii, 

, 1094 (9th Cir. 2002), and we affirm.

       Contrary to Arnsten’s contentions, the record shows that the district court

considered all of the facts submitted in opposition to defendants’ motion for

summary judgment.

       The district court did not err in granting summary judgment because the

undisputed facts show that Officer Clark had probable cause to make both the

October 5 and December 13, 2005 arrests, see Cabrera v. City of Huntington Park,

, 380 (9th Cir. 1998) (per curiam) (a finding of probable cause defeats

a claim of false arrest), and that Detective Cooper properly relied on information

obtained from Officer Clark in attesting to the facts in the Certification of Probable

Cause, see United States v. Jensen, 

, 704-05 (9th Cir. 2005)

(collective knowledge of police officers sufficient to establish probable cause).

       We do not to address the district court’s dismissal of the state law claims or

the claims against the City of Seattle because Arnsten did not develop arguments

regarding these matters in his opening brief. See Kim v. Kang, 

, 1000

(9th Cir. 1998) (concluding issues not specifically argued are deemed waived).

       AFFIRMED.
