What clued me in was three things:
1. The police sure as heck do not have time to call family on behalf of the arrested.
2. He started his sentences with little fillers. One of them was "now". Police don't talk like that. Unless he is some Explorer Scout trainee, police are trained to communicate in very clear, specific terms. If they are talking about a real crime or arrest, they don't need "nows" or "uhs".
3. When you get a bail bond, you have to deal with the bond company directly. The police are not affiliated with them in any way. They are private companies.
Plus, he never mentioned what the suspect is CHARGED WITH. What's the penal code violation? Police are going to have that or know it off the top of their heads.
I used to be the person who NEVER watched crime shows, and the crime shows of the 1970s and 80s were not that great, really, IMO. So, if this lady doesn't watch law or crime shows, how could she know arrest procedures, right? Nobody teaches us that in high school, BUT THEY SHOULD.
But the hesitancy and fillers in his talk is very un-police-like.
The other thing she could have asked was, "How can I speak to my loved one? I want to talk to him first."
