Facial Recognition Systems: More Hype Than Reality The technology behind facial recognition systems is still work in progress. Yet Delhi police used it extensively to "identify" and arrest people said to be behind the 2020 riots. outlookindia.com 2021-02-25T12:32:48+05:30 The February- March 2020 Delhi riots and the 2021 Republic Day violence caused an unprecedented strain on the Delhi police. In 2020, they had to attend to 16,000 distress calls and quell riots while being busy with US President Donald Trump’s visit. In comparison, the number of such calls during the first 4 hours of 26/11, the fiercest terror attack in our history, were 1365. Delhi police also had to investigate 755 criminal cases in 2020, resulting in 1825 arrests. Another report on February 23 said that 355 of the 755 cases are yet to be solved. Compare this with the FBI investigating 160 cases with 250 arrests for the January 6 White extremist attacks on the US Capitol Hill.
