Sure there are risks, I'm not debating that. But, you're putting an awful lot of clout into an officer who isn't an attorney and doesn't necessarily KNOW the law, (s)he's there to make a judgment call at the time and let the big wigs figure it out later. Even if you're found innocent, you really wanna spend a couple uncompensated hours of your day in the clink over it? What happens if that judgment call doesn't match what actually happened? I woudn't put a lot of legal faith in the "I called first"-defense either.
