Magaw didn't come up through the ATF but through the SS (Secret Service). He was head of Clinton's security detail, was elevated to SS chief (if I recall), and then was moved into ATF when a few marginally-culpable heads rolled after Waco. He then took charge of the cover-up/CYA operation and effectively protected the organisation from any consequences.
He was actually named ATF head as a reformer, but didn't reform anything. Similarly, his leadership of TSA has been a gravy train for old cronies. Tin ear doesn't half say it. The aviation press particular has been crucifying him (and he has deserved it). One of the first things he did was blow over $100k of the taxpayers' money on an audiophile sound system for his office. This is small as TSA waste goes, but it typifies the arrogance and snobbery that are now core Agency values.
One thing very typical of SS people is that they come to view Americans as existing in two classes: a Ruling/Master/Unchallengable class and a Ruled/Peasant-Serf/Threat class. This attitude has been imported into TSA wholesale. There are no good men in that org, and I think you will find that Loy is also one of Magaw's loyal Clintonistas, someone who sees ordinary Americans as bugs to be crushed.
