In fairness, a lot of fairly important details did not surface until today. It was an active case, after all. It is true that a lot of the will to act has come from the catalyst of Aaron's death, but the facts were not as clearly available before (IMO).
Edit : I should add that I believe there would have been a meaningful backlash had he for some reason lost his criminal case and been sentenced to (n > 3) years in federal prison.
In hindsight, there was a great deal of empathy to be shown to an individual who was being financially and emotionally drained by the legal system. However, that's the sort of stuff that doesn't readily occur to most people (myself included).
