What do you suggest the DA do? Trump up some Felony charges? Charge him with kidnapping without any chance of convicting him of it? Drop all charges?
YES. Either charge him with an actual crime, or drop the charges. This is politics, plain and simple. The DA has a high-profile case and is simply throwing a softball to make it look like his office is actually doing something, but nothing that'll result in any meaningful punishment.
Basically, ****, or get off the pot.
