The Brief: 1312 is the numerical translation of ACAB or "All Cops Are Bastards."
Similar to how the United States police force is commonly referred to as 12, 1312 is the numerical synonym to ACAB. It references how the letters A, C, A, and B are the 1st, 3rd, 1st, and 2nd letters in the alphabet. 1312 shares a negative perception of the police and relates to the growing animosity between the general public and the police in America. Twitter users have taken the numerical phrase and have attached it to their usernames.
