From what I hear, there is still some of the "cowboy" attitude in BATF and loonies wanting to run around in black ski masks and shoot people, but it has been largely contained and some "JBT" agents have been quietly removed. I think a lot of the credit is due to Magaw, who took over after Waco. His "We need to keep an eye on religions" quote got a lot of negative publicity (as it should have), but he was a competent administrator.
During the recent seizure of MKS rifles and receivers, there has naturally been a lot of resentment on the part of owners, but by all reports BATF agents have been calm and professional, with none of the threats and "we'll get you" attitude that was seen in the past.
We can only hope that the change is permanent. We may not like the laws they enforce, but we can at least respect them if they respect the rights of citizens.
