Breaking down the "Payphone" video by Maroon 5

In this video, we see Adam Levine, the lead singer of Maroon 5, steal a gun from a bank robber and rescue one of the employers. At 1:49, we clearly see him drop his gun and yet the police shoot at him. Instead of surrendering to the police and trying to clear up any misunderstandings, he steals a car and leads the police on a chase. So it's clear to both the audience and the protagonist that the police are out to get him. But the reason why isn't clear to the audience. I've narrowed it down to several theories. 1) They just found out that he is the bank executive who embezzled their pension funds. 2) They want to improve their marksmanship so that they are ready to face the actual bankrobbers 3) They are shooting at Adam Levine because fuck that guy.
