Dear Dr Fredrickson: 
Since there never was any evidence that recombinant 
DNA was any more hazardous than the organisms involved in 
its formation, and now there is plenty of evidence that it 
is not; I believe the NIH should adopt those policies to 
free the research and researchers from a totally useless 
bureaucratic mess. The proposal exemptions are a reason- 
able step in this direction, and should be followed by more 
until the NIH is completely out of the recombinant DNA 
business altogether. 
Yours sincerely.
