The Baltimore City Police Department, and the Baltimore County Police Department are separate entities. The City of Baltimore exists as a stand-alone, just like another county, in Maryland.
Rich, I agree with you that there has been no evidence supplied that would justify a "no-knock" warrant. However, all we seem to be hearing is the information released by the family's attorney, and the people in the house, wherever they were located during the incident. That through the filter of the media, a source of unimpeachable accuracy, right?
I also find it troubling that many are also already convinced that the outcome of the events, should they not be in favor of the deceased's family, simply means that the fix is in. Are we that close to thinking like the rioters in the Rodney King Trial?
