Motorcyclist wins taping case against Maryland state police - http://www.autoblog.com/2010...
"The judge ruled that police officers shouldn't have an expectation of privacy when engaged in a traffic stop -- "Those of us who are public officials and are entrusted with the power of the state are ultimately accountable to the public. When we exercise that power in public fora, we should not expect our actions to be shielded from public observation."" - Simon
