How far can you bully a cop before he can legally arrest you?

Trash talking a police officer is the usual response of gang bangers when the police are doing their job. You learn to ignore it. You don't use it as an excuse to bash people. Some people just don't know any better. If a person is breaking the law you either issue them a citation or make a custodial arrest. I have been sworn at by victims while pulling them from fires, wrecks,bar fights, and drug overdoses. Verbal abuse will not stop me from doing my job. When they get physically abusive then you use enough force to restrain them. Always remember to serve and protect. If you are looking for an excuse to bash people then law enforcement may not be the right profession for you. In order to get this job you will be background screened,polygraphed, and tested for psych. problems. Do you want to lose your job because of some childish name calling? I am sorry for the loss of your dad, but I hope I've answered your question.
