Too definitive?

[Charles Collins]

I admit that I have not given the HSCA report very much of my attention to date. So this a sincere question rather than a criticism. In its summary of findings, the HSCA say that the WC:

The conclusions of the investigations were arrived at in good faith, but presented in a fashion that was too definitive.

What is that supposed to mean? Does the HSCA get specific and spell this out for any particular conclusion?

Here is one of the HSCA recommendations:

The National Institute of Law Enforcement and Criminal Justice of the Department of Justice and the National Science Foundation should make a study of the theory and application of the principles of acoustics to forensic questions, using the materials available in the assassination of President John F. Kennedy as a case study.

My question:
A case study in how not to do it perhaps?
