He's human and makes mistakes just like anybody else and should be held to no higher or lower standard than anyone else. The law is the law and if they don't particularly LIKE the fact that there are laws he could have conceiveably broken then they should work to change the laws so he or they can break them again without so much going-on in the media.
It's not an issue of him being addicted - it's one of 'were the pills obtained legally?'. And it's not a matter of "everybody else does it and gets away with it so he should too" - whoever the person is: the law should be enforced. And even if it's only enforced once (whether or not it IS him) then that's just one more perpetrator punished.
He's driven me away from his show - it's not worth filtering through so much crap to hear the logical, conservative points being expressed. I can hear (read) all that stuff on the internet (like: here, among other sites) without sifting through all the garbage. I only get 30 minutes for lunch (the 2nd half hour of his show) and there are more and more days when there is absolutely NOTHING USEFUL in that time period. My time can be better spent than listening to useless b#llsh#t, so I tune elsewhere and get my news in the evening at home.
