The police can extract all data from phones

This is a type of machine used by the police to extract data from people's phones. Here's what she can find: call logs, chats, cookies, device notifications, emails, instant messages, passwords. You can see deleted conversations in encrypted apps like WhatsApp and Signal. Millie Graham-Wood, a lawyer at Privacy International, reviewing the extracted data, including Millie's deleted web browsing history, comments, "Hopefully [there's] nothing too compromising."

 The device also extracts the contact information of everyone she has been in contact with and the locations of all her calls. And you can see other people's phone numbers. When asked if it's possible to see their messages, Millie replies, "Yes."This means that the police receive information about people you have been in contact with who may have nothing to do with the arrest that may have occurred. Millie clarifies, "Exactly. And who could contact me confidentially at work using Signal." The most disturbing thing, according to Millie's interlocutor, is that "this can happen during an arrest, even when charges have not been filed." Millie adds, "It can also happen to witnesses and victims." There doesn't seem to be anything clear about deleting the data. "So it looks like the police can actually do whatever they want when they get your phone," Millie concludes.Another woman notes, "This is a frightening amount of information. She's also so useful to the police. It will be so important in the investigations." Millie agrees: "Of course. The problem is, at this point, you don't need a warrant to get it all." 

She stresses the need for control: "There must be a degree of involvement of the system of checks and balances that says, 'You know what, in this case it is not necessary or proportionate. You don't need this person's phone.'" This highlights serious concerns about privacy and lack of due process when using such powerful data extraction tools. 

The ability to access such a wide range of personal information, including deleted and encrypted data, without a warrant and clear rules of use and deletion raises serious questions about the balance between law enforcement and citizens' right to privacy.
