Maybe it was over your head, but the “equality” is in the means towards an end, though the crimes bear no similarity.
Drugs dealing would not be occurring without the clients. Likewise, without the “clients” for the leaks, there might not be any leaks or not much to speak of. Wikileaks is the client, and the leakers are/were within the government.
There isn’t a crime in reporting illegal behavior just because those criminals are high ranking government officials. That makes any such comparisons a stretch. Further, even in your pejorative fantasy analogy, wikileaks would be the dealer, the leakers would be the suppliers, and we the people would be the clients. But sure, if you want to make yourself feel better by saying it’s all over my head, go for it.
