I dunno...you must remember the Columbine cops who were all bundled up in their SWAT gear and wouldn't go in the building for hours, allowing victims to bleed to death inside while the perps were stone-cold dead.
That 'news conference' was so jam packed with information one would need to view it several times to get all of it!
That was a disgrace. We ought to have some sort of national standards or a national school for training all cops. Some of these PD's are clownish.
