For a start, crime scenes are covered in tents and shit here in the UK.
There would never be a scenario where a murder victim's body would be wheeled out in full view of the vultures press with Micronesia being poked in the faces of detectives as they go about their business.
Would that really happening the USA?
Because if it does then the USA is doing it wrong?
And another thing: our SOCOs (scenes of crime officers) here in the UK wear disposable jumpsuits and face masks to minimise contamination.
But apparently "Horatio" and his team don't have to.
