Bad Brunette Girl With Handcuffs

On occasions when a suspect exhibits extremely aggressive behavior, leg irons may be used as well; sometimes the chain connecting the leg irons to one another is looped around the chain of the handcuffs, and then the leg irons are applied, resulting in the person being "hog-tied". In a few rare cases, hog-tied persons lying on their stomachs have died from positional asphyxia, making the practice highly controversial, and leading to its being severely restricted, or even completely banned, in many localities. Most modern handcuffs in Canada, the United States, the United Kingdom and Latin America can be opened with the same standard universal handcuff key. This allows for easier transport of prisoners and keeps one out of trouble if one loses one's keys. However, there are handcuff makers who use keys based on different standards. Maximum security handcuffs require special keys. Handcuff keys usually do not work with thumbcuffs. The Cuff Lock handcuff key padlock uses this same standard key.
Somewhat recently, the Universal handcuff key was taken one step further, resulting in U.S. Patent # D454,774, a handcuff key which is readily accessible behind a police officer's breast badge. Invented by Michael Anthony Stahl, the device was licensed to the New York City Police Department in 2002. Stahl developed the key as a result of service as an Officer with Pinkerton's, Inc., in 1995, where supervision and transportation of work-release personnel was a daily occurrence. The device was updated to a simpler design in January, 2010, resulting in U.S. Patent # D607,305. It is known commonly as "The New York Tuning Fork", due to the shape and size of the key.
