‘Felony’ isn’t synonymous with ‘crime,’ it’s a particular degree of crime (“One of several grave crimes, such as murder, rape, or burglary, punishable by a more stringent sentence than that given for a misdemeanor,” according to the American heritage dictionary). Admittedly, I don’t have any real idea whether what either of them were charged with is actually a felony, but based on that definition, it sounds as though the answer to that is no.
I asked
kr’s in-house legal people once if the sentences
Courtney was getting were typical, or if any non-celebrity charged with such would be imprisoned already, and was surprised when the answer was that they thought it was typical – that anyone, with a prior record no worse than whatever
Courtney’s is would most likely have received exactly the same sentences. I haven’t asked this about Paris. But even as a non-lawyer I can easily see one big difference, which has already been mentioned several times here, the substance abuse factor.
