“The prosecutor asked the officer to demonstrate how he had flicked open the blade, as described in the officers sworn complaint: deponent opened the knife with centrifugal force by flicking deponents wrist while holding the knife, thereby releasing the blade which locked in place by means of an automatic device that did not require manual locking.
When I saw the officer use two hands to partially open the blade from the handle, where it had been snugly locked in the closed position, before his first flick, I knew my client was correct. I could enjoy the rest of the demonstration.
Holding the knife handle, the officer repeatedly whipped his wrist and forearm outward. Through the course of multiple flicks, the blade eventually rotated, at most, about 120 degrees, but never close to the 180-degree locked-open position. The officer tried multiple times, each time cheating from the partially open position. Each time with the same result.
I think his partner needs a new partner.
Spectacular!
I don't understand how police can keep their jobs after filing such obscenely fraudulent charges....
