outlined, there is no reason to believe that these guidelines 
cannot be altered, as the guidelines have been altered 
numerous times in the past. There have been many instances in 
which the guidelines prohibited certain classes of experiments 
until more was known about the risks. The existence of those 
prohibitions did not restrict policy discussions about these 
types of experiments, nor did they close off certain areas of 
inquiry. 
On behalf of the Committee for Responsible Genetics, I 
would like to thank you for this opportunity to share our 
concerns, and to bring this proposal before you today.
