I'm not sure why he needs to be on TV in the first place. His job is to prosecute whatever crimes happen to be occurring in his district. Instead, he cherry picks those that will make headlines in order to further his career. He is in the news vastly more often than any of his counterparts in other jurisdictions have ever been in the history of the DOJ. In short, he is abusing his office for personal gain.
Prosecutors are expected to look like zombies on TV?
(The comment I replied to was edited heavily after I replied to it)
I think its more that the application of professional makeup is indicative of a prosecutor overly concerned with appearance. Its not the touch up here and there to avoid looking like an overworked zombie, its the going to the extreme to look like a hero. The suggestion is that such vanity can get in the way of facts, truth and justice. I don't agree with this perspective, but I sympathise with it.
The implication that makeup and vanity have anything to do with one another in this context is suspect, though.
