The opinion
ROBB, Circuit Judge
(concurring):
I concur in Judge Fahy’s opinion, with one reservation. I reject any suggestion or implication that the Youth Corrections Act authorizes this court to disturb a lawful sentence imposed by a district judge in the exercise of his discretion and upon the basis of his in *1161 formed evaluation of the defendant. The review of sentences is not our business, and so long as the district judge exercises his discretion responsibly, after considering the facts and the statute, we may not substitute our judgment for his. The standards we have formulated must not lead to appellate intrusion into the sentencing process.
