Thanks for posting that.
The last thing I want to see is a murder-suspect escaping, and back on the streets...but I have to give the guy 'points' for his determination & success.
Apparently he was being filmed...but not watched (at least during those crucial moments).
They appear to be Peerless Hinged Cuffs...
Although a strong cuff, the video shows their weakness:
There is still enough flexibility between each cuff to allow "leverage" to twist & snap the hinges.
They only have two hinges...A S&W Hinged model has THREE (and the 3 hinges are shorter in length).
Decades ago, prisoners would escape by inserting the cuff's chain in, say, a seat belt buckle "hole"..and then twist their wrists until the chain link was sheared off.
In this case, the weak point wasn't only the handcuffs. By locking the cuff around a solid stationary object (the bar on the table)...that provided the leverage required.
If the cuff were locked around an object that was solid, yet free to spin or turn...this might not have happened.
It is doubtful anyone could have predicted this escape would happen.
Time for a re-design of the Peerless Hinged?
