London has made it easier for people to report crimes on public transportation.
Often times, identifying the person responsible for the crimes is difficult. According to Indy100, the Met Police and Travel for London have created a means to identify these people. According to BuzzFeed journalist Patrick Strudwick, police can use a debit or Oyster card number to track your location on a TfL vehicle. From there, they can find out which people were on board at the same time as you.
