Police and Tech Giants Wrangle Over Encryption on Capitol Hill WASHINGTON — Cyrus R. Vance Jr. <http://topics.nytimes.com/top/reference/timestopics/people/v/cyrus_r_vance_j...>, the district attorney of Manhattan, visited Washington late last month to argue his case on a pressing issue: encryption. In a string of meetings with members of Congress, Mr. Vance told <http://www.nytimes.com/2015/08/12/opinion/apple-google-when-phone-encryption-blocks-justice.html>central <http://www.nytimes.com/2015/08/12/opinion/apple-google-when-phone-encryption-blocks-justice.html>lawmakers <http://www.nytimes.com/2015/08/12/opinion/apple-google-when-phone-encryption...> that encryption needed to be diminished during criminal investigations. During a 45-minute session with Senator Angus King, an independent from Maine who is on the Senate Intelligence Committee, Mr. Vance said his office had 230 iPhones that might contain crucial information for cases but were useless because Apple <http://www.nytimes.com/topic/company/apple-incorporated?inline=nyt-org> refused to help the police break the encryption on the devices. “I wanted to express a sense of urgency around resolution of this issue,” Mr. Vance said in an interview about his Washington visit. A day after Mr. Vance <http://www.nytimes.com/2015/08/12/opinion/apple-google-when-phone-encryption...> was on Capitol Hill, tech executives including Kent Walker, the general counsel of Google, and Brad Smith, president of Microsoft, also met with lawmakers — but with a very different message on encryption. Tech executives at the meetings said they were concerned about any laws that would force companies to weaken the security of their technology, according to news officials representing these companies. <http://www.nytimes.com/2016/05/09/technology/police-and-tech-giants-wrangle-...> [...] after years of shrugging off the issue, Congress finally seems motivated to create a legal framework for one of our most critical digital security features. Here’s a quick rundown at some of the politicians who are shaping the encryption debate—and the laws that will come of them <https://www.wired.com/2016/05/encryption-laws/>
