US v. Williams, No. 15-10008 (9-20-16)(Wallace w/Kozinski & Whaley, Sr. D.J.).
The 9th reversed the suppression of a search of crack cocaine and a firearm. The 9th held that the officers had reasonable suspicion of the defendant from a tip, his actions, and possible offense (trespassing). The Gov't did not waive the argument that, after the initial stop for reasonable suspicion, probable cause for arrest was developed for violating a state statute (obstruction) that makes it unlawful not to flee and to give identity when suspected of an offense. The 9th upheld the officer's arrest of the defendant and the seizure of crack and a firearm.
The decision is here:
