Field PCR systems have been available for over a decade. The process takes 30 minutes to 1.5 hours based on the situation. It does not take days. I know this because I have used these systems in the field domestically conducting Pre, During and Post event Bio weapon surveys. Scratch that concern from your list.
As far as why? I believe it is common practice. It is somewhat akind to the civilian legal "chain of custody" efforts. He was targeted, He was found - engaged, killed, They took pictures of the target on site and the scene. They sweeped the immediate area for additonal intel, They took the body to a secure location, additional efforts to verify positive ID were taken, DNA samples were taken, Identity was confirmed, findings reported, the body was disposed of.
