No rudeness at all. It is the truth; our forensic services are not only 'cash strapped', but running on about 60% in terms of qualified staff etc (I might be wrong here, but the latest backlogs in terms of everything from fingerprints to DNA testing suggest the staff deficit could be even greater)
There are some incredibly dedicated officers, scientists etc: but their workload and the sever lack of funding does hamper them.
However, in this specific case, the initial investigation was a blind one - which means - you select the relevant forensic areas you FEEL will be most important, and you focus on those. (Oscar and his lack of detail in terms of story etc) This allows the police to at least direct their key personnel to areas they feel will be vital in terms of presenting a case and subsequent conviction.
In addition, the rather smart prosecutor (who has been around the block and then some) also knew that the accused in this specific case would spare no expense in hauling out every forensic test known to man in order to avoid conviction. Instead of doubling the workload, I believe the decision was to dovetail on whatever the defense presented, and either smash said tests on the cross OR: based on new evidence revealed by the defense, apply to re-open the state's case, in order to do the necessary to rebut.
In an ideal world the funding and facilities would be freely available. But with a president who has just done 'renovations' to the tune of 278 million Rand, and an election around the corner, money if tight. (Yet they found 3 million to fly Shrien in......)
Sad, but true.
In fact, most of the police experts sitting in court, probably have case loads of forensics that will seen them through to 2015 (and climbing)
