First of all, the cop had no right to stop the crowd. I presume mostly were curious kids and wananchi. Its not up to the police to protect people's private property if its in public domain unless from damage. just because you drive a fancy car does not mean that you ask the police to protect it from people who want to take selfies with it. That was a guy who had a superiority complex and felt that the cop should accord him and his a higher level of service.
