Semantics.
In this example, police still charge you, the prosecutor, or really it's often a magistrate, can decide to drop them. In Texas, it's commonly referred to as a "judge's card."
Rare.
We're talking about this case. They're not deciding whether to charge anyone in this case, because the DA has accepted the charged.
And for the cops to arrest you, they have to have reasonable articulable suspicion of a crime.
The cops can charge you and a judge or DA can dismiss the charges up front, but that rarely happens.
Anyway, I'm not going to argue over this. If you want to really know how it works, dig a little deeper.
I'm sure you're smarter than to think you can be arrested without cause...
What you're saying here is that the police can charge someone they've arrested and the DA or judge can decide to drop them in a certain amount of time. That's not what I'm arguing. I get that. I'm saying the cops just can't arrest you for no reason. They have to have probable cause you've committed a crime, then charge you with something.
There's all kinds of case law on this kind of thing.
