What is the test for violating section 69 of the Police Complaint Act?

"The first way of violating section 69 'encompasses attempts to deter either an officer's immediate performance of a duty imposed by law or the officer's performance of such a duty at some time in the future.' [Citation.] The actual use of force or violence is not required. [Citation.] Further, 'the statutory language [of the first clause of section 69] does not require that the officer be engaged in the performance of his or her duties at the time the threat is made." (People v. Smith (2013) 57 Cal.4th 232, 240-241.)
