I had lunch with a friend who had just arrived. His distant relative is a police officer in San Francisco and he told an extremely funny story about the trend associated with iPhones and new smartphones.
Further from his face:
Previously, when we caught, say, drug dealers, we tried to hack locked phones to get along with accomplices or, if it was a mercenary, customers. It was always hard and cost a lot of money even if the password was simple. Not one criminal said it voluntarily and we had to track calls through operators, that he was still a gamer or hack the entire phone.
However, after iPhones with fingerprints, it became easier because many criminals kept their fingerprints to open the phone and after a maximum of 20 attempts the phone was opened. We just stupidly tried all the fingers on our hands and feet. That many passed through and it happened that they specifically injured the right fingers during the delay, so that we could not open the phone and waste time hacking.
But after FaceID things went easy. You just take the detainee and direct a phone to him, which immediately opens up. So, a week ago, we arrested a cool but stupid dealer, and he, if we could not open his iPhone X, stumbled around the table on the site. The nose broke and a couple of teeth spit out... However, the iPhone still "recognized" him and he burned all his shareholders without wanting to : -)
Thanks to the technology :)
