Los Angeles: The information on these cards is used to help our officers memorialize what was said in field interviews and stay in contact with people who can help us solve crimes. Social media handles can be critical pieces of contact information, along with phone numbers and email addresses, because people communicate through social media now just as frequently as they do through calls, texts or emails. The LAPD is here to keep Angelenos safe, and we are committed to protecting their privacy rights as we confront that challenge every day.
