The other way around as well - officer's should show respect to citizens from the beginning as well.
This has mostly been my experience, except for some beach towns here, some small towns..... and Atlanta, GA. Atlanta has, from my experience, the least respectful officers of anywhere I've been.
Oddly enough, some of the friendliest I've met were in Lebanon. Though I don't recommend visiting (theres just something about seeing tanks in the streets of major cities that bothers me).
I agree wholeheartedly, but we have to understand that police officers have what is called "Legitimate Power," which in psychology means they are bestowed a presence of authority or knowledge that is universally accepted, and should be recognized by all law-abiding civilians. The intention of most officers is to keep everyone safe. They are in charge of any situation involving unlawful actions when they are present (as I've mentioned many times before, so long as their actions are lawful and constitutional) within their jurisdiction. If they ask you to sit down, out of respect, you should sit down. If they ask you to stop talking, out of respect, you should stop talking. If they ask you to do anything that would incriminate you, you should let them know you are aware of your rights and will not comply without yout attorney present. Of course it is up to you (and perhaps your lawyer) to assess whether they are being condescending out of arrogance (disrespect) or out of necessity (duty), but they should be given respect either way. When all is said and done, you can always press charges if you feel your rights have been violated, and remember, Miranda Rights and the Fifth Amendment apply to every American, not only those under arrest.
I'd be interested to hear an example of a police officer disrespecting you, SLD181.
