Security guards do not get any respect in our society. It is because we view them as false authority. Cops are already highly disliked. If you get take away the authority of the police, you basically have a security guard. So one can get the general idea of how they’re viewed by the public and trouble makers.
While cops are busy handling law breakers and giving out tickets, security guards in the cities usually wage war against the skate boarders and other riders that uses the outside of company builders for riding and doing stunts. Technically it’s against the law as it’s considered trespassing. However that does not stop some people from doing it and clashing with the security guards.
