What is the specific intent issue concerning threats to dissuade a witness from testifying?

[228 Cal.App.3d 1342] This court analyzed an analogous specific intent issue concerning threats to dissuade a witness from testifying, a violation of section 136.1, subdivision (c)(1), in People v. Ford (1983) 145 Cal.App.3d 985, 193 Cal.Rptr. 684. This Penal Code section is similar to section 139. It also proscribes malicious threats on witnesses or victims. We concluded that section 136.1, subdivision (c)(1) was a specific intent crime that was committed whether or not the witness did or did not testify. (Id. at pp. 989-990, 193 Cal.Rptr. 684.)
