When Apple introduced the new Activation Lock anti-theft system with iOS 7 to help prevent the re-use of stolen iOS devices, some lawmakers saw it as the perfect way to help quell smartphone theft. In fact, many sought to make features like it standard on all mobile devices. Today, the New York Times has released some new numbers that shows a decrease in iPhone theft following the implementation of Activation Lock.

According to New York police, thefts involving Apple products have dropped by 19% in the first half of 2014 compared to the same period in 2013. London and San Francisco authorities have seen even more impressive drops, with 24% and 38% reductions in iOS device thefts, respectively, in the six months following the feature’s release when compared to the six months immediately preceding it.

In April, Apple joined with other smartphone manufacturers and cellular carriers in an agreement to add similar features to all new mobile devices.
