I think if you see them commit an offence, right in front of you, you're probably still good, but that offence had better be on the bigger side and have a clearly defined victim (most likely you) before you even think of calling. Aggravated trespass? Loitering with intent? Following you for no plausible reason? I'm afraid his knife/dick has to be put in you before you make that call, Karen.
If I see a Mexican or African American commit a crime I cannot call 911? Cali is insane.
