Bloomberg is not your guy.

"In total, 1,806 people were arrested during the [Republican] convention. Some were legal observers and members of the press. Some were mere bystanders who unwittingly encountered protesters while walking in the city and got swept up in indiscriminate mass arrests. 'I was just walking by –– I had a receipt from a store that I had bought something from on that street' V'epa Majamutar told Democracy Now some 12 hours after her arrest. 'All of a sudden the street basically just gets cordoned off and we cannot move. So before I was arrested I was just standing still because that's all we could really do. And then they just started putting handcuffs on people. They gave us no warning.'"
